How much did you pay for mining
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
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
web link post bar example:
we will calculate the graphics card to dig bitcoin earnings
assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s
HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days
OK, all the parameters are ready, calculation
in calculation...
eh, how come it's a negative number
because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low
suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950
Mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
3, users use personal computer to download software, and then run specific algorithms. After communicating with remote server, they can get corresponding bitcoin, which is one of the ways to get bitcoin. Ordinary graphics cards don't need to try, and electricity charges are not enough. Master Lu has bitcoin test, which can see how long it takes for your computer to dig a bitcoin
It depends on the source of the mine. If it is an "open pit mine", the investment is relatively small. The main investment is the wages of workers and the cost of transportation road construction. If the ore is deeply buried, the investment needs to be larger. In addition, the acquisition of mining license is also a part of the investment, and this is the main part. If there is no mining license, the others are always empty
To sum up, the main investment costs are as follows:1, workers' wages
2, machinery and equipment
3, transportation road construction and maintenance costs
4, mining license fees
5, and other costs
