Market Analysis on April 24, 2020: The Halving Market of BTC Will Come, And the Number of New Transaction Addresses Has Reached A Peak in 2 Years

[Today's Hot Tips]
1. [The halving market of BTC will comes, and the number of new transaction addresses has reached a peak in 2 years]
During the short-term change in BTC prices, trading volume returned to a high of $ 42 billion. Judging from the current market performance, performance of BTC is good, and it is a currency with a slightly higher increase in mainstream currencies. In other words, the short-term lead effect of BTC is prominent, and investors actively participate in BTC transactions, which is why the market has begun to ferment.
The data show that not only the market investors trading activity is high, but also the number of new OTC trading users is increasing. That is to say, the market fermentation is the result of investors on the market and OTC simultaneously seeing more. Combined with the fact that BTC is getting closer and closer to the time of reducing production, the current activity has prompted more signals of market fermentation.
2. [Tether added 360 million USDT pre-additional issuance transactions to the additional issuance transaction pool last night]
The chainsmap monitoring system of Chainsguard found that at 21:04 on April 23, Beijing time, Tether added three 120 million USDT pre-additional transactions to the ERC20 USDT additional issuance transaction pool, totaling 360 million USDT.
[Today's market analysis]
BTC continued to sideways above 7500 USDT in the early hours of this morning. It rose slightly at about 6 o'clock and briefly touched 7600 USDT. It is now oscillating above 7500 USDT. Mainstream currency follow the sideways, with small fluctuations. BTC is currently reported at 7520.2 USDT on LOEx Global, with an increase of 0.02% in 24h.
Late last night, the pie BTC finally pulled up 5.87% at the last moment when it ran out of the runway, decisively breaking through the shock space and choosing the direction upward.
The overall trend of Bitcoin's daily k-line cycle is upward, and the lower support line is still the upward support line formed by the connection of support levels 7200 and 7500. If this support line is intact, after the technical side breaks through the recent convergence pattern, the overall trend of the daily K-line cycle is upward, and the currency price may form a larger consolidation upward channel with the upward support line formed by the connection of7500 and 8000.
All this stems from the fact that with the end of April, the halving effect in May increased the incremental capital for admission, and the number of account openings reached a new high. The halving of Bitcoin will definitely have a positive effect on the price in the long run, but this advantage will not be reflected in the price so quickly. From last year's Litecoin halving, it started a bad start. This year, BCH halved, BSV halved, and the price fell after halving. This will give a bad psychological hint to short-term investors who really use funds to buy Bitcoin. When the good is realized, there may be a short-term bearish, but the long-term will be good.
Operation suggestions:
Support level: the first support level is 7400 points, the second support level is 7200 integers;
Resistance level: the first resistance level is 7800 points, the second resistance level is 8000 points.

How much would a Bitcoin node handling 1GB blocks cost today? I did some back-on-the-envelope calculations.

1GB blocks would be able to confirm more than 5000tx/s. That would be VISA-level scale (which handles, on average, 1736tx/s). We often hear that we shouldn't raise the blocksize because then nodes would become too expensive to run. But how expensive exactly?
We have the following costs to take into account:
For now, I'm going to assume a non-pruned full node (i.e. a node that stores all transactions of the blockchain) for personal use, i.e. for a computer built at home. I'll add in the calculations for a pruned node at the end, which would likely be the prefered option for people who merely want to verify the blockchain for themselves. If you don't care about the assumptions and calculations, you can just jump right to the end of this post. If you spotted any error, please inform me and I'll update my calculation.

Storage

There's, on average, one block every 10 minutes, that is 144 every day and 4320 blocks every thirty days. I was able to find a 3TB HDD for $47,50 on Amazon, that is $0.018/GB. Storing all blocks with all transactions of a month (4320GB) would be $78.96/mo. Prices for storage halved from 2014 to 2017, so we can assume that to half in 2022, thus we can reasonably assume it'd cost around $40/mo. in 2022.
But would such an inexpensive hard disk be able to keep up with writing all the data? I found a comparable cheap HDD which can write 127MB/s sequentially (which would be the writing mode of Bitcoin). That would be enough even for 76GB blocks!
Edit: For the UTXO set, we need very fast storage for both reading and writing. Peter__R, in his comment below, estimates this to be 1TB for 4 billion users (which would make ~46,000tx/s if everyone would make 1tx/day, so id'd require about 10GB blocks). jtoomim seems more pessimistic on that front, he says that much of that has to be in RAM. I'll add the $315 I've calculated below to account for that (which would be rather optimistic, keep in mind).

Bandwidth

Bandwidth is more complicated, because that can't just be shipped around like HDDs. I'll just take prices for my country, Germany, using the provider T-online, because I don't know how it works in the US. You can plug in your own numbers based on the calculations below.
1GB blocks/10 minute mean 1.7MB/s. However, this is an average, and we need some wiggle room for transaction spikes, for example at Christmas or Black Friday. VISA handles 150 million transactions per day, that is 1736tx/s, but can handle up to 24,000tx/s (source). So we should be able to handle 13.8x the average throughput, which would be 1.7MB/s x 13.8 = 23.46M/s, or 187.68Mbit/s. The plan on T-online for 250Mbit/s (translated) would be 54.95€/mo (plus setup minus a discount for the first 6 months which seems to cancel out so we'll ignore it), which would be $61.78/mo. This plan is an actual flatrate, so we don't have to worry about hitting any download limit.
Note, however, that we don't order bandwidth for only our Bitcoin node, but also for personal use. If we only needed 2MB/s for personal use, the plan would be 34.95€, thus our node would actually only cost the difference of 20€ per month, or $22.50/mo. Nielsen's Law of Internet Bandwidth claims that a high-end user's connection speed grows by 50% per year. If we assume this is true for pricing too, the bandwidth cost for ~200Mbit/s/mo. would go down to 12.5% (forgot how exponential growth works) 29.6% of its today's cost by 2022, which decreases our number to $2.81/mo. $6.66/mo.
Edit: jtoomim, markblundeberg and CaptainPatent point out that the node would have a much higher bandwidth for announcing transactions and uploading historical blocks. In theory, it would not be necessary to do any of those things and still be able to verify one's own transactions, by never broadcasting any transactions. That would be quite leechy behaviour, though. If we were to pick a higher data plan to get 1000MBit/s downstream and 500MBit/s upstream, it would cost 119.95€/mo., however this plan isn't widely available yet (both links in German). 500MBit/s of upstream would give us max. 21 connected nodes at transaction spikes, or max. 294 connected nodes at average load. That would cost $39.85 in 2022 (with correct exponential growth).

CPU/Memory

CPU/Memory will be bought once and can then run for tens of years, so we'll count these as setup costs. The specs needed, of course, depend on the optimization of the node software, but we'll assume the current bottlenecks will have been removed once running a node actually becomes demanding hardware-wise.
This paper establishes that a 2.4GHz Intel Westmere (Xeon E5620) CPU can verify 71000 signatures per second... which can be bought for $32.88 a pair on Ebay (note: this CPU is from Q1'10). We'd need to verify 76659tx/s at spikes (taking the 13.8x number), so that pair of CPUs (handle 142,000tx/s) seem to just fit right in (given one signature per tx). We'd also have to account for multiple signatures per transaction and all the other parts of verification of transactions, but it seems like the CPU costs are neglegible anyway if we don't buy the freshest hardware available. ~$100 at current prices seem reasonable. Given Moore's Law, we can assume that prices for CPUs half every two years (transistor count x1.4162), so in three years, the CPU(s) should cost around $35.22 ($100/1.4163).
For memory, we again have to take into account the transaction spikes. If we're very unlucky, and transactions spike and there won't be a block for ~1h, the mempool can become very large. If we take the factor of 13.8x from above, and 1h of unconfirmed transactions (20,000,000tx usually, 276,000,000tx on spikes), we'd need 82.8GB (for 300B per transaction).
I found 32GB of RAM (with ECC) for $106, so three of those give us 96GB of RAM for $318 and plenty remaining space for building hash trees, connection management and the operating system. Buying used hardware doesn't seem to decrease the cost significantly (we actually do need a lot of RAM, compared to CPU power).
Price of RAM seems to decrease by a factor of x100 every 10 years (x1.58510), so we can expect 96GB to cost around $79.89 ($318/1.5853) in 2022.
Of course, CPU and memory need to be compatible, which I haven't taken into account. Chug a mainboard (~$150) and a power supply (~$50) into the mix, and the total would be just over $600 for today's prices. Even if mainboard and power supply prices remain the same, we'd still only have to pay around $315 for the whole setup in 2022.

Electricity

I found the following power consumptions:
So we'd have 129W 147.6W + N*6W. Electricity cost average at 12ct/kWh in the US, in Germany this is higher at 30.22ct/kWh. In the US, it would cost $11.14 $12.75 + N*$0.52 (P*12ct/kWh / 1000 * 24h/day *30days / 100ct/$), in Germany 28.06€ 32.11€ + N*1.30€.
At the end of the first year, it would cost $20.12 $21.73/mo. in the US and 50.52€ 54.57€/mo. in Germany.
At the end of the second year, it would cost $29.11 $30.72/mo. for the US and 72.98€ 77.03€/mo. for Germany. It increases by $8.98/mo. per year in the US and by 22.46€/mo. per year in Germany.
Electricity prices in Germany have increased over time due to increased taxation; in the US the price increase has been below inflation rate the last two decades. As it's difficult to predict price changes here, I'm going to assume prices will remain the same.

Conclusion

In summary, we get:
If we add everything up, for today's prices, we get (E: updated all following numbers, but only changed slightly) $132/mo. (US), $187/mo. (DE) for the second year and $71.92/mo. $78/mo. (US), $115.79/mo. $124/mo. (DE) in 2022.
It definitely is quite a bit of money, but consider what that machine would actually do; it would basically do the equivalent of VISA's payment verification multiple times over, which is an amazing feat. Also, piano lessons cost around $50-$100 each, so if we consider a Bitcoin hobbyist, he would still pay much less for his hobby than a piano player, who'd pay about $400 per month. So it's entirely reasonable to assume that even if we had 1GB blocks, there would still be lots of people running full-nodes just so.
How about pruned nodes? Here, we only have to store the Unspent Transaction Output Set (UTXO set), which currently clocks in at 2.8GB. If blocks get 1000 times bigger, we can assume the UTXO set to become 2.8TB. I'll assume ordinary HDD's aren't goint to cut it for reading/writing the UTXO set at that scale, so we'll take some NVMe SSDs for that, currently priced at $105/TB. Three of them would increase our setup by $315 to $915, but decrease our monthly costs. E: However this UTXO set is also required for the non-pruned node, therefore the setup costs stay at $915. Even in the highest power state, the 3 SSDs will need only 18.6W in total, so we'll get a constant 147.6W for the whole system.
In total, this is:
In total, this is $35.25/mo. in the US and $58.57/mo. in Germany for today's prices, or (E:) $19.41/mo. (US) and (E:) $42.73/mo. (DE) in 2022's prices. Which looks very affordable even for a non-hobbyist.
E: spelling
E²: I've added the 3 NVEe SSDs for the UTXO set, as pointed out by others and fixed an error with exponentials, as I figured out.

NPIP004: Static Block Reward

After the ClockSync fix was soft forked into the network a couple of months ago, NavCoin is now compliant with the Proof of Stake v2 protocol as published by Blackcoin:
https://blackcoin.org/blackcoin-pos-protocol-v2-whitepaper.pdf
The next logical step is to become compliant with PoS v3. The spec can be read here:
https://bravenewcoin.com/assets/Whitepapers/Blackcoin-POS-3.pdf
The short version is that PoS v3 includes cold staking capability and a fixed block reward.
We have already presented cold staking in NPIP002 and it has received unanimous support from the community. This is scheduled to be deployed after the Community Fund claims mechanism goes live and brings NavCoin half way to being compliant with PoS v3.
This brings us to the second part of the PoS v3 spec, a fixed block reward.
Why would we want a fixed block reward instead of a percentage based reward? The main consideration is that while earning stake rewards is nice for your NAV balance, the primary purpose of staking is being rewarded for validating and securing the network. With the current percentage based rewards, coins can be offline for an indefinite period, not securing the network, then appear online to claim their reward even though they have done very little work to secure the network beyond minting a few blocks.
Coins which are online are using their weight to validate blocks minted by other stakers and play an important part in securing the network, even if they're not the one minting the current block. They are what protects the network against a 51% attack and it is therefore important for network security to have as much coin weight online as possible.
To read the full rationale, please refer to NPIP004 here: https://github.com/NAVCoin/npips/blob/npip-0004/npip-0004.mediawiki
Please remember that this is a draft at this stage and is open for discussion. Ultimately no-one can alter the consensus mechanism without support from the network, so the choice will be up to the community and network to decide the best course forward. I want to put a few additional thoughts on paper here which I would love some feedback on.

Overview

NPIP004 suggests to set the static block reward at 2NAV per block.
There are approximately 1,051,200 (2*60*24*365) blocks mined per year which means there would be 2,102,400 NAV generated per year by proof of stake rewards.
There are currently ~63M NAV in circulation, so this would set the inflation rate to 3.3% annually by way of stake rewards. The other thing to take into consideration with a static reward is that as a percentage, it will exponentially decrease over time.
eg. When the circulating amount is 100M NAV, the inflation generated by stake rewards would be the same amount of NAV which equates to 2.1% of total supply instead of 3.3%.

Deflationary supply

There is some debate whether an exponentially deflationary supply is a good or a bad thing. In regards to supply demand economics, it has proven to be a massive boon for Bitcoin with the value exponentially increasing after every mining reward halving. The counter argument is that it is bad for distribution since it rewards early adopters more than the new entrants to the ecosystem.
Personally, i'm the for the deflationary model. I think the difference in mining rewards from now until we have 100M in circulation (10+ years from now) is negligible compared to adoption when we're talking about things which effect the supply demand economics. It is reducing by 1/3 over roughly 10 years, not halving every 4 years as with bitcoin.

Inequality

There has been some discussion as to how this could drive a further divide between stakers with more and less NAV. The thing to keep in mind is that although the rewards are fixed, the number of blocks you stake is still proportional to your staking weight on the network. This means that stakers still increase in wealth proportionally to each other as a percentage. Let's run a few scenarios.
Assuming there are 20M NAV contributing to staking, just like there is today. Here's what the stake rewards would look like for some different balances over a 1 year period.
Balance After 1 Year Percentage
1,000,000 NAV 1,105,120.00 NAV 10.512%
100,000 NAV 110,512.00 NAV 10.512%
10,000 NAV 11,051.20 NAV 10.512%
1,000 NAV 110.512 NAV 10.512%
As you can see, the only real thing that happens is we shift the decimal place around if we have different input values, but as a percentage everyone is increasing proportionally to what they input.
This is a slightly over simplified view, but it is largely accurate. Whether you have 10% or 0.001% of the total staking weight, you will mint blocks proportionally to your weight, so everyone's balances increase at the same percentages.
The only thing which could complicate the matter is compounding interest. A few people have been concerned that because the person with the larger balance stakes more frequently, they will effectively run away from the smaller stakers who would never get the opportunity to stake.
I wrote a small computer program to simulate the staking rewards over 1 year taking into account the network weight and the additional 2 NAV added every time someone finds a block. The assumption I've made is the worst case scenario e.g all coins staked are never spent, but compound back onto the staking weight.
You can read the program here: https://github.com/craigmacgregostatic-reward-modelleblob/mastemodel.js
In laymans terms, it calculates when you'd be due for a reward based on your weight vs the rest of the network where the network starts with 20M NAV and gets 2 NAV added per 30 seconds. The output is as follows:
Staker Balance Start Balance End Percent Gain
balance1 1,000,000 1,105,120 10.51%
balance2 100,000 110,512 10.51%
balance3 10,000 11,052 10.52%
balance4 1,000 1,106 10.6%
network weight 22,102,400 10.51%
So, as you can see the smaller stakers still get their rewards, even though the bigger stakers balance is going up 2NAV every 20 blocks. I even modelled this for someone staking 100 NAV and they will end up with 112 NAV after 1 year (12% gain). So if anything it seems like this model marginally favours smaller stakers over bigger ones which was a surprising result actually.
The only thing this doesn't take into account is resolving orphans. I can't simulate orphans easily with a basic javascript program, it is something I will investigate when i run the NPIP on the testnet to make sure there is no problem in the real world. But i assume it will be of little consequence.

Why is it over 10% gain?

You have to remember that because the total amount generated is fixed but split proportionally. With a network weight of 20M the annual rewards per coin is 10.5%, but if 40M coins were staking the annual reward per coin would be 5.25%. if more people bring coins online to stake, the rewards decrease. Currently there are only around 25% of NAV online for staking, but typically we see around 40% NAV online for staking which would mean the annual reward is around 8.4% per coin. If 100% coins were used for staking the annual reward would be equal to 3.33% per coin.

How does this compare to other coins?

Coin Reward
PIVX 5-10%
ARK 10-12%
LSK 10%
NEBL 10%
NAV 5-10%
Source: https://www.investinblockchain.com/best-proof-of-stake-coins
So this move would put us in step with other PoS coins and actually still remain on the low end of the reward scale, especially if more people start staking.
I found this spreadsheet which has pretty detailed information about a bunch of coins and their inflation rates:
https://docs.google.com/spreadsheets/d/1-weHt0PiIZWyXs1Uzp7QIUKk9TX7aa15RtFc8JJpn7g/edit#gid=237137882
From this, you can see that NavCoin would still have one of the lowest inflation rates in crypto when you include PoW coins as well. Bitcoin currently inflates at around 3.68% as example.

Isn't low inflation like we have now better?

With 4% per year and only 25% of coins staking, NavCoin currently only inflates at around 1.4% per year (including the community fund). We've seen the staking network weight roughly halve over the last 6 months, something which could be attributed the reduction of rewards when the community fund was introduced. It's possible people are switching to other, more profitable PoS coins because 4% reward is too low. At this network weight and market rate, it would only take around USD $2M worth of coins to perform a 51% attack. In reality, buying enough coins to 51% attack the network would drive the price of NAV up and therefore make it much more expensive than this to attack the network, but it's still worth noting the importance for network security to attract more people to stake.

Conclusion

Changing to a static block reward of 2 NAV per block increases network security in multiple ways, the first being that it forces people to be online securing the network with their weight constantly. Secondly, it would increase potential earnings for stakers which would attract more people to stake NavCoin and increase the network weight further. Both of these factors make the network harder to 51% attack and would improve network security.

Additional suggested changes

When we originally proposed 0.25 NAV per block for the Community Fund we calculated that as 20% of the current inflation rate. So reducing from 5% to 4% and adding 0.25 NAV was roughly equal. However this calculation was based on 40% of coins staking at 5% reward. I would suggest that if we move to a static block reward, we increase the community fund amount to 0.5 NAV per block, so it retains the 20% ratio to staking rewards as was originally intended.
This would mean that there are 2,102,400 NAV created per year for staking and 525,600 NAV per year created for the community fund totalling 2,628,000 new NAV created per year. This equals an initial inflation rate of 4.17% which is exponentially decreasing as a percentage as explained previously.

Alternative approaches

Maximum Coin Age
We could introduce a maximum coin age of 1 month. If they came online after 6 months to claim reward, they would only receive 1 months of reward. This would incentivise people to remain online because otherwise they would miss out on rewards. However, for a big staker, they can cycle thorugh all their coins quite quickly, but a small staker would potentially miss out on rewards even if they stayed online the whole time. I would argue this solution is worse for small stakers than a static reward. It also doesn't address the fact that other coins have higher rewards and attracts no new users.
Block Validator Reward
We could keep the coinage based staking rewards for the block minter and create an additional static reward which the minter issues to people who are online and securing the network with their weight even if they aren't the block minter. It would still essentially be a lottery based on network weight, but this way we have a hybrid system where everyone gets their percentage, but people who are online staking all the time get extra. This alternative would take a reasonable amount of investigation, research and testing to accomplish and it's not been trialled before afaik. For simplicities sake, i would argue that just using a static reward is a better option.
Other approaches
Not sure what else, i haven't thought of any other ways to solve this problem yet. If you have any ideas, don't be afraid to post them in the thread.

Conclusion

I'm personally in favour of changing the block reward to 2 NAV and increasing the Community Fund to 0.5 NAV per block. I'd be happy to hear your thoughts, so please post your feedback below.

Bitcoin’s Record Hash Rate May Hint at Price Gains to Come

Bitcoin’s Record Hash Rate May Hint at Price Gains to Come


Article by Coindesk: Omkar Godbole
Bitcoin’s latest bout of consolidation may end up with bullish breakout, as a key metric of miner confidence has hit all-time highs.
The top cryptocurrency by market value has clocked lower daily highs and higher daily lows over the last three days and is currently trading at $10,300 on Bitstamp, little changed on a 24-hour basis.
The cryptocurrency has charted the narrowing price range amid a surge in non-price metrics including a rise in the network’s hash rate — a measure of the computing power dedicated to mining bitcoin.
The two-week average hash rate reached a record high of 85 exahashes per second (EH/s) around 19:00 UTC last Friday. Further, mining difficulty — a measure of how hard it is to create a block of transactions — also jumped to a new all-time of nearly 12 trillion.
The hash rate could be considered a barometer of miner’s confidence in the bitcoin price rally. After all, the miners would be ready to dedicate more resources for mining if they are bullish on price and would want to scale back their operations if a price slide is expected.
Hence, many observers, including the likes of Changpeng Zhao, Founder of Binance, and former Wall Street trader and journalist Max Keiser believe prices follow hash rate.

https://preview.redd.it/vapgqlijqgn31.png?width=660&format=png&auto=webp&s=f7dbc990a6f6f57cbbf16ce2bbafa193e49a8acf
Zhao tweeted on Friday that, “a rising hash rate means more miners are investing in BTC”, while few other observers stated that sellers should think twice before betting against the most secure blockchain — the higher the hash rate of a cryptocurrency network, the more expensive to 51 percent attack.
Put simply, Zhao is expecting bitcoin’s price to track the hash rate higher. It is worth noting that the market stands divided on the relationship between bitcoin’s price and hash rate.
Some observers believe the hash rate follows price and the metric’s outperformance represents overtly exuberant miners. Hence, reading the rising hash rate as a sign of an impending price rally may prove costly.
That said, the price is likely to follow the hash rate this time, as overexuberance is typically observed at market tops or near record highs. As of now, BTC is down almost $10,000 from the record high of $20,000 reached in December.
Also, the market sentiment is quite bullish with reward halving (supply cut) due in less than a year and the sustained uptick in miners’ confidence is more likely to draw fresh bids, possibly leading to a positive feedback loop.
All-in-all, the narrowing price range established over the last few days is likely to pave the way for a bullish move.

Daily and 4-hour charts


Bitcoin has charted (above left) back-to-back inside bar candlestick pattern over the last three days. The first inside bar appeared on Friday as that day’s high and low fell within Thursday’s trading range.
The second and the third inside bar candle was created on Saturday and Sunday, respectively.
Inside bars indicate consolidation and lack of volatility and often end with an explosive move on either side. A break below the first inside bar’s (Friday) low of $10,154 would imply range breakdown and could yield a stronger sell-off to levels below $9,855 (Sept. 11 low).
A break above Friday’s high of $10,458 would imply range breakout and open the doors to $10,956 (July 20 high).
The falling wedge breakout confirmed on the 4-hour chart (above right) last week is still valid. So, the probability of range breakout is high.

The Second LTC's Halving is Coming, Will it Continue the Strong Performance?

The Second LTC's Halving is Coming, Will it Continue the Strong Performance?


[58COIN] The price of Litecoin(LTC), the cryptocurrency largely considered to be the silver to Bitcoin’s gold, recently rose steadily in the upcoming of the mining reward halving.
Litecoin’s Halving Expectation Doubles the Price of LTC
Litecoin, as the world’s fifth largest cryptocurrency, the price was down about 85% from all-time highs. However, LTC has rallied steadily since early 2019. According to 58COIN, the price has clocked to a high of nearly $60 until March 20, increased by nearly 100% compared with $30 at the beginning of 2019.
Are You Ready for the Upcoming Mining Reward Halving?
Recently, the news about the mining reward halving spreads, most people hold the thought that halving mining means that the miners will get fewer coins, and then the price will definitely rise. The max supply of LTC is 84,000,000, the circulating supply is 60,000,000, the remaining 24 million will affect the market price to some extent.

https://preview.redd.it/b17l582ssfn21.jpg?width=540&format=pjpg&auto=webp&s=fa3fb9b355bc96de51ef3392b465be3145938067
  1. Halving will cause changes in supply and demand.
  2. Halving will double the cost of mining.
  3. History shows that each halving is accompanied by a skyrocketing in price:
In the first half year of the Litecoin’s first halving, the increase was over 500%, but the market environment was different at that time. In addition, comparing the BTC’s second halving, that is, the market of July 10, 2016, the highest rise was 112%. At present, LTC has risen more than 100% from the low level, can it exceed 5 times of the first halving?
How to Invest in the Upcoming Halving?
The halving market is divided into the expected market and the skyrocketing market. Based on the previous halving of BTC and LTC, the expected market is mainly due to the reluctance of miners to sell, generally starting three to six months before halving, with a small increase lasting about two months.
Investors can buy low six months before the halving and hold the position for 1–2 years after the halving, then sell high when the bull market reaches the peak. Don’t rush to sell until the real halving market starts.
The halving is expected to occur on August 8, 2019. According to the law, the expected market will start 3–6 months in advance. Therefore, it may begin in March to May this year, that said, you can buy low in batches from now on.
Please be aware that the above views are based on the previous market performance and regularity of BTC and LTC before and after halving, and does not mean that LTC will also rise sharply after this halving. Investors should conduct your own research before investing.

Bitcoin Mining Primer

I have been helping a friend develop business strategies at a Bitcoin start-up over the last few months. In the course of this work, the topic of Bitcoin mining appears often to be fraught with misinformation and uncertainty, especially for individual miners who unfortunately may find it difficult to return an adequate profit in many cases. This informal guide covers some important issues prospective miners should consider to avoid headaches and financial loss. The information is derived from experience deploying a 400 TH/s system scheduled to come online in around December. Opinions are my own; I’m happy to entertain constructive feedback.
This year, the Bitcoin network will award miners nearly USD 500 million, at the current price of USD 375 per bitcoin, to participate in a process known as mining. Unsurprisingly, this has attracted significant interest not only from Bitcoin advocates, but from speculators and investors as well. Regardless of one’s motivations, the business of Bitcoin mining must ultimately be profitable, or at least operationally viable, if there is to be any chance of success.
HOME MINING
Acquiring and personally managing ASIC miners is probably the most fulfilling way to mine bitcoins. It provides the greatest level of transparency, but requires a certain level of technical proficiency to set up and run.
Advantages:
1) No hosting fees payable
2) Full control of operating parameters
3) Direct payment from mining pool
Disadvantages:
1) Purchasing the latest mining hardware is inherently risky because the ongoing development of energy-efficient ASIC chips requires expertise, time and millions of dollars. R&D is usually funded by customer prepayments with no guarantee of timeliness or success. It is not uncommon for miners to incur financial loss and opportunity costs when a supplier fails to deliver
2) The retail price of hardware is typically marked up anywhere from 25% to 500%, or more, depending on market conditions. This creates a barrier to profitability, making it harder for miners to recoup hardware costs if they are unable to negotiate for volume discounts
3) Shipping fees and import tariffs can cost hundreds of dollars per unit, especially if importing equipment from overseas. This adds to the cost of hardware and must be taken into account when calculating the return on investment
4) Shipping time varies greatly. Each day spent in transit incurs an opportunity cost
5) Miners need to set aside space, usually in the home, to locate mining equipment
6) Many mining units may generate excessive noise, and heat that requires around the clock ventilation to maintain an optimal operating temperature range
7) The average mining unit draws up to three amps of current. A system containing twenty units could easily exceed the power limit in a typical home
8) Electricity is by far the largest expense in any mining operation, making up around 90 percent of operating costs. If the price of residential power is materially higher than the rate paid by commercial operators, it makes home mining uncompetitive
CLOUD MINING
Buying into a cloud mining service is often marketed as a convenient and hassle-free way to get in on Bitcoin mining. As the mining assets are managed by an intermediary, getting a breakdown of operating costs prior to purchase often proves difficult. This makes it challenging for potential customers to make a fully informed buying decision. The unspoken truth is that some cloud miners incorporate obsolete equipment—cheap miners from previous generations or liquidated, unprofitable hardware—into their cloud to sell to unsuspecting customers. Older mining units can consume 80% more power than the current generation miners, leaving very little profit for the customer. In addition to the acquisition price, those in the market for cloud mining should consider the power consumption of the cloud on offer, including changes over time as new mining units are added to increase total capacity.
Advantages:
1) Start earning immediately. No waiting weeks or months for equipment delivery, installation and set up
2) Convenient and fully managed mining service means customer needs not be technically inclined or involved in day-to-day operations
3) Professional hosting service ensures optimal performance and low operating costs. Commercial hosts may be able to purchase electricity for a materially lower cost than residential customers
4) Acquisition price is often reasonable. Sometimes, possibly, too good to be true
5) Some platforms allow miners to sell their assets to other traders
Disadvantages:
1) Not all hashing power is comparable. For the same acquisition cost, more energy-efficient miners are better because they use less power and return higher profits. When buying hashing power from a cloud, the buyer should ensure he is not getting obsolete hardware. Often this is not possible to verify without a basic understanding of the costs involved, however subpar earnings is a good indication that further investigation is required
2) Hosting and cloud management fees are typically payable. Sometimes there is little transparency in pricing, resulting in unexpected cost to the customer
3) Miner has little input into how the cloud is managed
COSTS BREAKDOWN
The amount of money earned from Bitcoin mining over a short period of time, say one week, is fairly easy to calculate. Given mining is a zero-sum game where new entrants dilute existing participants and the mining reward is roughly shared on the basis of each miner’s contribution to the overall hash rate, we can derive profit by estimating the income and costs.
Mining Income:
Weekly mining bitcoins created = 25,200 = 25 bitcoins x 6 times per hour x 24 hours x 7 days
Assuming hash rate is at 300,000 TH/s, bitcoins earned weekly per one terahash of processing power = 0.084 bitcoins = (1 terahash/ 300,000 terahash) x 25,200 bitcoins
Table 1: Weekly earnings per one terahash of computing power
Hash rate (TH/s)....Bitcoins earned 270,000.... 0.0933 280,000.... 0.0900 290,000.... 0.0869 300,000.... 0.0840 310,000.... 0.0813 320,000.... 0.0788 330,000.... 0.0764 340,000.... 0.0741 350,000.... 0.0720 360,000.... 0.0700 370,000.... 0.0681 380,000.... 0.0663 390,000.... 0.0646 400,000.... 0.0630 
As new miners enter the market, an increase in hash rate dilutes the mining reward. This is the source of much uncertainty in mining because it is difficult to accurately forecast the rate of increase. Dilution reduces a miner’s income while the amount of work is the same.
Mining Costs:
Electricity typically comprises around 90 percent of total operating costs. The two determinants of electricity cost are price and the amount of electricity consumed.
If we take a hypothetical 700 GH/s system that is rated at 490 watts, we can normalise it:
0.7 kW per one terahash = (1 terahash / 0.7 terahash) x 0.49 kW
Electricity used per week is:
117.6 kWh = 0.7 kW x 24 hours x 7 days
If we know the cost of electricity, the dollar value of electricity consumed in one week can be estimated. For reference, power prices in Australia are between USD 14 cents (commercial rate) and 19 cents (residential rate). China averages around 8 cents, while other places can be cheaper. For example, in Georgia, USA the cost of commercial electricity is around 6.5 cents per kWh.
Table 2: Weekly electricity cost of running a one terahash system
 Cost at different power ratings (USD) Electricity price (USD/kWh).....1.1 kW...0.85 kW....0.7 kW 0.05.... 9.24.... 7.14.... 5.88 0.06.... 11.09.... 8.57.... 7.06 0.07.... 12.94.... 10.00.... 8.23 0.08.... 14.78.... 11.42.... 9.41 0.09.... 16.63.... 12.85.... 10.58 0.10.... 18.48.... 14.28.... 11.76 0.11.... 20.33.... 15.71.... 12.94 0.12.... 22.18.... 17.14.... 14.11 0.13.... 24.02.... 18.56.... 15.29 0.14.... 25.87.... 19.99.... 16.46 0.15.... 27.72.... 21.42.... 17.64 
Other costs to consider include mining pool fee (typically 1 percent of earnings), hosting fee (depends on host) and other expenses such as air conditioning if hosting at home, maintenance, etc.
Profit:
Using the assumptions that hash rate is at 300,000 TH/s and bitcoin price is USD 375, we can work out the profit. Moreover, knowing the basic cost of Bitcoin mining can help prospective miners avoid offers that are too good to be true. To simplify, we ignore other running costs:
Profit = (bitcoin price x bitcoins earned) - electricity expense

 Weekly profit in USD (300,000 TH/s hash rate) Electricity price (USD/kWh).....1.1 kW...0.85 kW....0.7 kW 0.05.... 22.26.... 24.36.... 25.62 0.06.... 20.41.... 22.93.... 24.44 0.07.... 18.56.... 21.50.... 23.27 0.08.... 16.72.... 20.08.... 22.09 0.09.... 14.87.... 18.65.... 20.92 0.10.... 13.02.... 17.22.... 19.74 0.11.... 11.17.... 15.79.... 18.56 0.12.... 9.32.... 14.36.... 17.39 0.13.... 7.48.... 12.94.... 16.21 0.14.... 5.63.... 11.51.... 15.04 0.15.... 3.78.... 10.08.... 13.86 
These figures serve as a good benchmark for comparing your personal performance. Where the electricity price is known, the difference between the calculated and actual profits can be attributed to two things:
1) Energy efficiency of mining units can cause significant deviation, especially when the cost of electricity is high. This is usually the case if obsolete equipment is being used
2) Hosting fee, mining pool fee and other costs also contribute to the difference
Return on Investment:
The rate of return is a measure of how much miners make for a given investment size.
Implied annualised return = (52 weeks x profit per week) / (hardware cost + shipping fees + tariffs + installation and setup costs)
The current price of ASIC miners runs at around USD 500 per terahash, excluding international delivery and insurance that can cost between five to 20 dollars per kg ($50 to $200 per unit). As a general rule, higher operating profit and lower capital costs are preferred. Investors endeavour to break even quickly on the initial hardware investment and make a profit on top of that.
The problem with this model is that it implies the hash rate remains unchanged for the entire year. In reality, the hash rate is likely to increase depending on a variety of factors. Therefore, the annual profit forecast is sensitive to changes in the hash rate as well as bitcoin price. This is a complex and interesting topic that deserves its own post. Please, keep in mind that actual mining results will very likely be less than what is indicated by this simple calculation. Under some scenarios, even informed miners can experience financial loss.
OPERATING RISKS
1) Liquidity risk: Bitcoin trading is rather shallow. As such, miners may experience high trading frictions when selling bitcoins to obtain cash. A bid-ask spread of up to 10% is not uncommon in some cases. Furthermore, most mining businesses rely on the liquidation of mined bitcoins to cover operating expenses such as electricity and hosting. The combination of these two factors may result in unexpected trading costs to the miner if there is insufficient demand from bitcoin buyers.
2) Price risk: Bitcoin is highly speculative and this is reflected in its price volatility. There is no guarantee that it won’t be worthless by next year. Therefore, the miner should keep in mind that the market price is just as important as the amount of bitcoins he holds. Bitcoin price is influenced by multiple factors outside of the scope of this discussion.
3) Competition risk: Bitcoin mining is a zero-sum game. While the size of the reward is fixed, new entrants are permitted to enter at anytime reducing all miners’ share of the reward. When bitcoin price is high, more new competitors are attracted to mining, further eroding all participants’ income.
4) As a function of the Bitcoin protocol, the mining reward will be halved between May and June of 2016. When this happens, all miners will experience an immediate decline of 50 percent in income with many operators becoming unviable. This effectively gives new entrants less than 1.5 years to break even and turn a profit. The short window of opportunity is troublesome because it makes mining significantly less profitable as the deadline draws near.
