Bitcoin mining in Africa

The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />

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

Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

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

At present, bitcoin needs to be g by professional mining machines. 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

according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation

extended data:

because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners

the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin

I think there is still a market for bitcoin mining, but from the era when ordinary computers can participate in bitcoin mining to today's mines, miners all over the world compete in computing power at the same time. With the increasing number of miners, the difficulty index of the game is getting higher and higher, and it depends on their strength to play it in the end. If you want to open a mine, then the basic costs include mining machinery, electricity, maintenance, labor, mine rental, etc., and the only source of income is to replace the bitcoin with legal currency. Mining machinery will be lost, bitcoin prices will fluctuate, and electricity charges will rise, all of which are uncontrollable
