Contract mining

1.

mining is a nickname for the exploration method of acquiring bitcoin. Because of its working principle is very similar to mining minerals, so named. In addition, bitcoin explorers who do mining work are also known as miners

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 the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer

extended data:

to be a miner, just "mine" bitcoin and search for 64 bit numbers by computer. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network

if the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. It needs to create a fixed number of bitcoins per unit of computing time. It can get 25 bitcoins every 10 minutes

by 2140, the upper limit of bitcoin in circulation will reach 21 million. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging< br />

2. 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

3. At present, most of the mainstream Ethereum mining machines in the market come from bitmainland and Jianan Yun. However, with the decline of Ethereum's price, the profits brought by mining have been very meager. Investors can choose to invest in Ethereum on the digital currency exchange. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.

Return once an hour, return the mining output 24 hours ago and in the same hour interval.

there are more than a dozen other companies. There are too many words to post. Let's see for ourselves

continuous update: trade is mining! The most complete list of mining exchanges in history

5. The reason for computing power contract is that bitcoin mining has become more and more professional, and mining has higher and higher requirements on site and technology. Personal mining has become no longer relaxed and pleasant
therefore, computing power trading platforms like 58hash emerge as the times require. Users only need to purchase computing power, trust computing power to the computing power trading platform, pay a certain maintenance fee, and the computing power hosting platform will uniformly maintain the mining machines, and issue the extracted bitcoin to users on time.

6. Two years of old users to answer this question to you, computing bee does not affect the real name of the purchase and revenue output, real name authentication to use the time is to pick up the money can be, and dig the money is always ready to buy and sell transactions, very convenient.

7. I think it's very good, but it's better to experience it in person. The service charge seems to be lower than that of other exchanges, and the platform also gives fmex to trade and sell.
