Point to point mining

3.

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

5. At present, the most popular way of bitcoin trading is contract trading. According to the rise and fall of the price, it is far better to obtain income than the traditional mining and direct trading. After all, there is no need to really hold virtual currency, just need to judge whether the price is up or down, which is very suitable for the existing investors, simple and convenient

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

7. Mining is to confirm the transactions in the bitcoin system over a period of time and record the process of forming a new block on the blockchain. The miner is called the miner. In short, mining is the process of bookkeeping, the miner is the bookkeeper, and the blockchain is the ledger. How to motivate the miner to mine? The bookkeeping power of bitcoin system is decentralized, that is, every miner has the right to keep accounts. The miner who successfully seizes the bookkeeping right will get the new bitcoin reward of the system. Therefore, mining is the process of procing bitcoin. When Nakamoto first designed bitcoin, it was stipulated that for every 210000 blocks generated, bitcoin rewards would be halved until bitcoin could no longer be subdivided. Because the total amount of bitcoin is limited as gold, bitcoin is called digital gold, and bitcoin proction is also commonly known as mining
. The bitcoin system ensures that bitcoin will not be g out too quickly by adjusting the difficulty coefficient. Every 10 minutes, the whole network is absent from work to jointly calculate a difficult problem, compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will be g out soon. In order to ensure that bitcoin can be g out in about 10 minutes, Nakamoto designs the difficulty of mining for bitcoin, Every 2016 blocks (about 2 weeks) are dynamically adjusted, so that the difficulty after adjustment makes the expected time for each block to be generated 10 minutes. Now the difficulty coefficient is about 480ph / S (Note: September 2017), which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer, Generate a new block
. Compared with point-to-point trading, mining and other purchases on the trading platform are the most popular ways to obtain blockchain assets, that is, floor trading. Floor trading of blockchain assets is similar to stock trading. The platform can help you match up, and you don't need to know who your trading partner is. Your trading partner may be one person or many people, Whether it's buying or selling, the trading platform will record the hanging order price of everyone. The buyer and the seller can obtain the latest transaction price through the real-time order. At the same time, the trading platform will summarize the historical transaction price and volume into a K-line chart, which is convenient for investors to analyze the market trend. For example, the UTOR market is the mainstream trading platform in the world.
