Btc20t computing power

1.

mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K

now the basic unit is GH / s, and several hundred g mining machines are very common

[bitcoin mining machine]

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world

2. Bitcoin and bitcoin cash (BCH) have the same mining mechanism. Miners will choose whether to dig bitcoin or bitcoin cash according to the level of mining income. It is a normal phenomenon that bitcoin computing power increases and bitcoin cash computing power decreases
in short, it is a redistribution of computing power driven by interests.

3. Firstly, the cost of bitcoin mining can be divided into three parts:
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.

4. Of course, it is awesome to be able to get on the cloud.

5. At present (2017 / 03 / 23), 1t computing power can dig about 0.00055 bitcoins a day. According to the current currency price, a 1t computing power miner can dig about 4 bitcoins a day. About 0.002 bitcoins can be g in 3.65t1 days, which is about 15 yuan in RMB. However, it is not fixed how much bitcoin can be g every day. Generally speaking, with the continuous upgrading of mining machinery, mining machinery developed by mining machinery manufacturers will continue to be put into the market, and the computing power of the whole network will continue to grow over time. The proportion of your computing power in the computing power of the whole network will graally decrease, and the bitcoin g by the corresponding computing power will also continue to decrease. In addition to purchasing mining machines to build and deploy mines, you can also purchase computing power on computing power platforms such as suanlibao, which can be used as an entrance to understand bitcoin, mining and blockchain. At the same time, you can also have considerable benefits under the condition of accepting risks.

6. For example, when I buy a miner with 20000 tons of computing power, the cost is 1000 tons. The one who sells cloud computing power is to buy a machine with 2000W, 20 tons of computing power, 1000 tons of computing power. He sells 13001500 tons of computing power. In short, cloud computing power is not reliable. The one who sells cloud computing power is to earn the price difference of mining. It's better to buy a miner to dig

7. This is definitely a loss.
recently, I saw a test that the rtx3070 notebook only earns 1.2 yuan an hour.
1050ti computing power is less than 1 / 4 of 3070, which is about 24%
power consumption is 35% of 3070.
energy consumption is not cost-effective. One hour's income is definitely less than 1 yuan, except for the electricity charge. Once the loss of notebook is eliminated, it is definitely a loss
