There are also people digging in Hong Kong, but Hong Kong people will not dig on the main island of Hong Kong, but will go to some major power generation provinces where electricity prices are cheap.

First, what is mining:

There are two tasks to be done when mining node computers: the second task of mining node computers is real mining, that is, computing encrypted hashes, solving a computing problem and competing for computing power. Among many nodes vying for bookkeeping rights, whoever completes this calculation first, its packaged block is added to the end of the blockchain and becomes the latest block. The first miner to complete the calculation will win the mining award for the new block. Initially, if a block is successfully dug up, miners can get 50 bitcoin rewards. According to the rules, this mining reward is halved every four years, which is 25, 12.5, and so on. Let's discuss two more questions to get a deeper understanding of Bitcoin's workload proof mechanism and its mining mechanism.

Second, how to trade mineral coins:

1, OTC

Over-the-counter trading is a personal transaction. Some websites offer such trading methods, just like Taobao. Some people hang some business orders on the website. If you are satisfied with his order, you can deal with him. It is worth noting that you should try to choose some sellers/buyers with large trading volume and good trading credit, so as not to be easily deceived. However, some big websites have relatively mature systems, which are quite good on the whole.

Step 2 exchange transactions

The second category is exchange transactions. It is worth noting that exchange transactions cannot complete the conversion from virtual currency to legal tender (that is, RMB, US dollar and other legal tender) like over-the-counter transactions. Generally, it is traded with usdt, which is a virtual currency, but usdt and USD are 1: 1, which means that its value is the same as USD. Many exchanges provide transactions from legal tender to usdt, which means that transactions need to be conducted with usdt at exchanges.

Third, why do you want mine graphics cards?

1. The so-called "mining" is actually to confirm the transactions that occurred in the Bitcoin system for a period of time and record them on the blockchain. In short, miners are like "miners". Mining is bookkeeping, and "miners" are bookkeepers.

2. In the early days of Bitcoin's birth, it was possible to mine by computer CPU. However, with more and more people mining, the computing power of CPU was obviously insufficient, so everyone began to mine with professional diggers.

3. Bitcoin mining machine is a professional equipment that competes for bookkeeping rights through a large number of calculations to obtain bitcoin rewards. For miners, what needs to be done is to ensure the power supply and network connection of the mining machine.

4. Compared with professional mining equipment, our ordinary graphics card mining has less investment and quick results. And graphics cards can be seen everywhere, as long as you have a good performance graphics card, you can participate in mining.
