China mines 200000 a year

1.

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

2. Erdos, 560 kilometers west of Beijing, is covered with hot waves and sandstorms. The gate is a dividing line, separating the two worlds. Outside the gate is a typical landscape of China's fourth tier Urban Development Zone, while inside the gate is a science fiction scene like the matrix. Eight large factories with blue roofs are juxtaposed. Tens of thousands of "mining machines" are flashing red and green light and roaring in the factory, making digital currency bitcoin for this "mine" day and night. This once the world's largest mine holds about 4% of the computing power (proction capacity) in the bitcoin world. During the peak period, it can dig out more than 100000 bitcoins a year, which is worth more than 3 billion RMB at the price of 30000 RMB in August 2017.
bitcoin was invented by "Zhongben cong" in 2009, Using the computing power of the chip, the boring and repetitive process of constantly "hash collision" in the blocks generated by the bitcoin system to win the bookkeeping right and thus obtain the system reward of bitcoin is vividly called "mining" in the bitcoin instry, and the professional staff engaged in this work are called "in the first few years of bitcoin operation, An ordinary laptop can play the role of "mining". However, the entry of Chinese miners has completely broken the balance of this situation. Relying on professional mining machines designed and made in China, they staged one after another bitcoin world computing power arms race, raising the threshold of "mining" tens of thousands of times

3.

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

4. At present, bitcoin mining still exists in China, but e to the stricter regulatory policies, many miners have left. Because it may be difficult to make money in the future.

5. In Shanxi,
is not a big mine. There are more than 30 million tons of coal mines in Pingshuo and Luliang< The profit mainly depends on the cost. Generally speaking, the comprehensive cost of coal mining in private coal mines is relatively low. The profit is relatively high. The cost per ton of coal is about 200 yuan. If the coal type or quality is good, the raw coal can also be sold at a high price. The quality of clean coal after washing is better. The price is also higher
simply calculate, if raw coal can buy 400 yuan per ton, the profit will be 200 yuan per ton. 500000 tons, just one billion
if you wash jiadandan zheganfei and surpass Jianggong, the price of clean coal will be higher and the profit will be higher
private
more than 5 million tons is very powerful

6. Hello, it's OK. You can find some mines here to cooperate and make money

7. One T + 1, one T + 0, choose the second without hesitation
secondly, bitcoin has a perfect derivative route, which can accurately hedge risks. What about a shares? We have to buy up and wait for the harvest

bitoffer offers the strongest bitcoin option and is the best risk hedging tool in the spot

how to use options to hedge the fall risk of spot

for example, the current price of bitcoin is US $10000
if it goes up to US $11000, the spot profit is US $1000
if it goes down to US $9000, the spot loss is US $1000

if you open a put option hedging in bitoffer, the cost is only US $20. If bitcoin goes down from US $10000 to US $9000, the spot loss is US $1000, and the put option profit is US $1000, The two offset each other, your account does not have any loss, this is the charm of hedging

after opening the hedging mechanism, your account will make money if it goes up, and even if it goes down, because the risk has been completely offset.

8. In fact, it's a bit impossible. There are many people who make more money, but there are only one or two in China's billion, not to mention the large number of people like Shanxi. In Taiyuan, there are many rich people, but there are many poor people - and there are many poor people. You know, the GDP of Taiyuan, the capital of Shanxi Province, is not as good as Nanchang, which is very poor, because there are too many poor people!

9. Illegal mining, according to the criminal law and relevant judicial interpretation, is basically more than five years if there is no legal commutation.
