21 day challenge of bitcoin life
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
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

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
after two consecutive days of plummeting, according to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, on June 13, Beijing time, the price of bitcoin fell below $6500, the lowest level since February this year. Bitcoin used to cost $6463. Since the beginning of this year, cryptocurrency has faced more and more resistance. Bitcoin, which has the largest total market value, has been fluctuating since it reached a record high (nearly US $20000) in December last year, with a cumulative decline of about 50% this year
from the United States, South Korea, Japan and other governments' supervision of cryptocurrency to the prohibition of cryptocurrency trading by visa, Bank of America and other large financial institutions, and to the prohibition of cryptocurrency advertising by internet giants such as Facebook, Google and twitter, the price of bitcoin has been aggravated by the recent multiple bad news
several exchanges were stolen
on June 10, coinrail, the cryptocurrency exchange of South Korea, was attacked by hackers, and more than US $40 million of unknown cryptocurrencies such as pundi
x were stolen. Subsequently, the prices of bitcoin, Ethereum, reborn and lightcoin all dropped more than 10% in one day
on June 29, 2017, bithumb, the largest bitcoin exchange in South Korea and the top five in the world, was found to have been hacked, and more than 30000 customers' personal information was stolen. According to the market value at that time, the loss amounted to 7.6 billion won
on January 26, coincheck, the largest trading volume exchange in Japan, suspended the trading of all cryptocurrencies except bitcoin. The trigger was that hackers attacked 260000 users and stole NEM, a new digital token, with a loss value of about US $530 million
bitcoin is likely to graally lose its loyal fans
bitcoin is now a widely recognized financial asset in the financial market, and many factors will lead to its price fluctuations, such as the expectation of the Federal Reserve to raise interest rates. At present, this round of price adjustment is still in progress since the beginning of the year. After all, in 2017, the price of bitcoin soared more than 20 times
bitcoin has been sold. From December 2017 to April 2018, bitcoin worth 30 billion US dollars has been sold. According to chainalysis, bitcoin's market liquidity has increased by nearly 60% in recent months. Bitcoin is likely to be losing its fans
the initial growth of bitcoin does rely on loyal fans. In recent years, the demand for investment has increased. However, bitcoin is still an asset with strong consensus foundation in the blockchain field, and long-term holders may waver. However, when they find that other cryptocurrencies are more risky, bitcoin may return to the vision of investors
since the beginning of the year, the price of bitcoin has been in a bear market cycle. At present, the bear market is still going on, and the periodic rebound will be obvious, but the overall situation is still in a weak adjustment. The probability of further weakening is relatively large, but the space will be relatively small.
I think this is more serious than the loss, but it should have little impact on our real currency. Because the two are not related . The currency of the virtual world is a game created by capitalists in order to converge the wealth of people in the real world. But no matter how we ordinary people speculate, we can't change the fate of these capitalists. They often dominate the changes in the war situation, turning their hands into clouds and covering their hands with rain. But no matter what they do, it should have little impact on the real world currency, otherwise governments will not allow them to exist
Therefore, changes in the bitcoin market will not affect the value of our real currency or other aspects. Even if there is, the governments of various countries will also vigorously suppress and try to rece the impact in this regard, so we should relax our mind strong>How do you define gambling? If it's legal, investing in bitcoin is not a gamble. Investing in bitcoin is as legal as investing in stocks and futures, and the price of bitcoin is no longer as crazy as it was a few years ago. Just pay attention to the risk when speculating em>
