What is the average cost of BTC
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
It's about 37 yuan
let me first introce the reward mechanism of bitcoin system
bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years
at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin
about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc
The impact of the okex incident on the currency market is fading; With the US election becoming increasingly white hot, the difficulty and hash rate of bitcoin are higher than before
in terms of price, so far, BTC has rushed to around us $11720, with a 24-hour increase of more than 2%
so the question is: where will bitcoin go in the next week
here are five factors that may affect the BTC price trend in the coming week
No.1 US macro level: election and stimulus plan this week, the US is the absolute focus of the macro market. The US presidential election will soon usher in a decisive moment (November 3)
analysts warn that if the Democratic Party (Biden) wins, the dollar will depreciate - and the long-term outlook for the dollar is already precarious. Goldman Sachs said last week that Trump's re-election was not enough to get the dollar out of danger
however, no matter what the election result is, professionals recommend buying gold as a hedge. However, in the view of others, bitcoin may bring more profits
However, e to the inverse correlation between BTC / USD and the dollar currency index (DXY), the strength of the US dollar, in the view of some bitcoin traders, will still affect the price trend of bitcoin. Although this correlation has become less and less obvious in recent weeks, the sudden weakness of the US dollar is still likely to be a boon for bitcoin

at the same time, not only the election, but also what happened before is also a topic of interest. Specifically, a coronavirus stimulus plan was in place before polling day
If this happens, trillions of dollars of liquidity will increase the growing debt pile of the United States, and Americans will see additional benefits, such as an additional $1200 economic stimulus planNo.2 Europe suggests more intervention
with the outbreak again, the European Central Bank (ECB) is considering further measures
European Central Bank President Christina; In an interview with Le Monde on Monday, Lagarde said the European Central Bank would use more financial instruments if necessary
the European Central Bank's coronavirus stimulus program has purchased a total of 1.5 trillion euros of assets
"We haven't run out of options in our toolbox yet," says Lagardebrexit is increasingly moving towards "no agreement" brexit, which makes the possibility of instability worse
No.3 the fundamentals of bitcoin have reached a new high
recently, bitcoin has maintained a strong resilience in the face of various black swan events. Influenced by okex, BTC recently dropped below $11200, but recovered steadily soon. So far, it has exceeded $11600
and on the technical level, the fundamentals of bitcoin also maintained a record strength this month
two days ago, the difficulty of the latest adjustment increased by 3.5% than expected
at the same time, the hash rate also climbed to a record high on Monday. At the time of publication, the estimated computing power for mining is 146 exahashs (EH / s) per second
as often reported in the media, the popular theory is that the price follows the hash rate, because the long-term investment prospect of bitcoin is better than ever before

No.4 analysts focus on $12000 BTC price breakthrough
for famous analyst Micha & # 235; For Lvan de Poppe, the key price conversion of bitcoin is becoming more and more reasonable
in his latest video update on Sunday, he stressed that the significant resistance level of weekly closing price below US $12000 for several consecutive years will soon end
Van de Popper believes that since the beginning of the bear market in early 2018, US $12000 has become the rejection point of the weekly chart, but the consolidation below cannot last forever
he concluded: "we are likely to rebound to the range of US $16000 to US $17000, because this is the obvious level and the last obstacle for bitcoin to begin to break through the all-time high."
after this move, there will be another consolidation period, which may last longer than the current period
van der BOPP added that he advised viewers to work hard to accumulate bitcoin, even in the $16000 range

No.5 market sentiment: greed is back
with the graal strengthening of prices, investor sentiment is also changing: data shows that investor sentiment is becoming more and more greedy. In the latest market data, the fear and greed index has returned to the "greedy" area, rising slightly from "neutral" in the past week
this indicates that bitcoin investors' emotional expectations will be bullish, but it should be noted that if the price rises too fast, "greed" will become "extreme greed", in which case the index is more likely to callback
bitcoin features: no freezing, no tracking, no tax, and extremely low transaction cost. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
at present, the mainstream digital currencies include bitcoin, Ethereum, bitcash, EOS, Ruibo, etc., which can be properly invested, and the transactions are risky, so we should invest cautiously.
1. Prepare the bitcoin you want to send. The client is responsible for collecting the balance of bitcoin in your wallet (bitcoin QT) to prepare for payment, because every bitcoin you receive is stored in your wallet until you spend it. If you receive two payments from 3btc and 2btc, their records in the wallet are independent of each other, that is, a 3btc and a 2btc, rather than merging them into 5btc (the wallet only records transaction details and does not merge the balance, but you can see the total balance on the interface of the wallet). As time goes on, many bitcoins of different amounts will accumulate in your wallet, So when you send bitcoin, the wallet has to decide which bitcoin is the most suitable for this sending. The bitcoin you get in a transaction is called "inputs" and the bitcoin you spend is called "outputs". There are multiple inputs and outputs in your wallet
2. If your outputs are less than 0.01btc (including the fund changes inside your wallet), you have to pay a handling charge of 0.0001, even if you transfer it to yourself. The wallet has an established rule when preparing your payment amount, that is, when preparing the payment amount in many inputs, try to avoid the amount change less than 0.01btc (for example, if you want to pay 5.005btc, the wallet should choose 3 + 2.005 or 1 + 1 + 3.005 instead of 5 + 0.005)
3. The larger the amount, the higher the age, and the higher the priority. If the amount you send is too small or your bitcoin has just been mined, then your transfer is no longer free. Each transaction will be assigned a priority, which is determined by the degree of currency, the number of bytes and the number of transactions. Specifically, for each input, the client will first multiply the number of bitcoins by the time they exist in the block (currency age, age), and then divide all the procts by the size of the transaction (in bytes). The calculation formula is: priority = sum (input)_ value_ in_ base_ units * input_ age)/size_ in_ If the calculation result is less than 0.576, then the transaction must pay the handling fee. If you do have a large amount of small input and want to transfer it out for free, you can add a large amount of bitcoin with a large age, which will increase the average priority, so that you can transfer out bitcoin for free
4. Charge per kilobyte. At the end of the transfer, the client will detect the size of the transfer (in bytes). The size generally depends on the amount of input and output. The calculation formula is as follows: 148 * input amount + 34 * output amount + 10. If the size of the transfer exceeds 10000 bytes, but the priority meets the free standard, you can still enjoy the free transfer, Otherwise, there will be a handling charge. The cost of 1000 bytes is 0.0001btc by default, but you can also add it in the client. Open the tab "settings & gt; Options & gt; The main purpose is to adjust the handling charge. If the service charge you are setting is less than 0.0001, BTC is calculated as 0.0001.
a $5 bitcoin transaction may have the same handling charge as a $5000 bitcoin transaction. Fees are not measured in dollars, not even in the number of bitcoins
they are measured by "satoshis". Satoshis is the smallest unit of bitcoin: 100000000 satoshis = 1btc
instead of paying for every bit of bitcoin you send, you are actually paying for the space your transaction occupies in the block. The average transaction size is 226 bytes, so the time to confirm the transaction depends on the cost of the transaction
The service charge of okex bitcoin exchange is the lowest in the world, ranging from 0.15% to 0.02%, and there is no charge for platform currency okb
in bybit, for each successful order, bybit platform will automatically decide to charge or provide rewards according to the order attributes. For "market makers" in the market, the system will give 0.025% reward based on the contract value for each successful price limit order
for the "price receiver" in the market, the system will charge 0.075% of the contract value based on the contract value for each successful market order. A $5 bitcoin transaction may have the same handling charge as a $5000 bitcoin transaction
