Current production of bitcoin

1. 1、 bitcoin is an experimental currency, and the consensus of core members is that bitcoin is only a virtual experimental currency. Its existence value is to prove whether money must have thing value or only need a currency symbol. If it survives, and can always be used as a trading chip, then the proof of money does not need physical value, as long as a reasonable currency symbol. If it can not survive, then the proof of money must have a certain physical value. 2、 Bitcoin is "mined" by calculating the results of mathematical problems. I think you can pay for bitcoin to get an answer to a math problem. You know, computing resources are valuable, and many people don't realize it.

2. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. The biggest difference between bitcoin and other virtual currencies is that the total number of bitcoin is very limited and extremely scarce. The total number of bitcoin is about 21 million. At present, 17 million bitcoins have been mined
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

3. The total amount is 21 million, about one block is proced every 10 minutes, and the number of bitcoins in each block is 12.5 after being halved twice, that is to say, 12.5 bitcoins are proced every 10 minutes

4. There are two main reasons for the decrease of bitcoin output of bitcoin miners:

1. With the increase of computing power in the whole network, the proportion of computing power owned by miners in the whole network decreases
2. The generation of bitcoin is slowing down. When bitcoin was born in 2009, each reward was 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 bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. In theory, bitcoin's mining speed has halved in four years.

5. Theoretically, the block reward generated every day is 12.5 (number of rewards per block) * 6 * 24 (6 blocks per hour, 24 hours per day) = 1800btc
bitcoin network generates one block every 10 minutes on average, and the reward for each block is currently 12.5. At the earliest time, 50 BTCs were awarded to each block, which was halved after 210000 blocks were excavated, about once every four years. It is expected that the next halving will be in May 2020, when the reward for each block will become 6.25

6. Every time bitcoin is halved, there is indeed a surge. But if you have studied bitcoin, every surge has a cycle, that is, it will not surge immediately after the proction rection. There is a long process, which may take one or two years
for reference only, it has no practical significance. After all, I don't count.

7. Are you talking about bitcoin? If you are talking about other cryptocurrencies, I can only tell you that most of them are deceptive and pyramid schemes

bitcoin is also proced by mining. Mining is the process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary

however, at present, the profit margin of mining is very small, and the mining cost has approached or even exceeded the currency price. Now mining is mainly about electricity price and energy consumption. Of course, it also needs the support of faith. Go to bitcoin home to learn some basic bitcoin knowledge, so as not to be cheated.

8. First of all, suppose that coin a throws a positive coin, the probability is 1 / 2, and coin B throws a positive coin, the probability is 1 / 2. Then the probability of throwing two coins with the same positive coin is 1 / 2x1 / 2 = 1 / 4
similarly, the probability of throwing a coin with the same negative coin is 1 / 4
add the two cases: 1 / 4 + 1 / 4 = 1 / 2
