1. 1. bitcoin adopts a decentralized mechanism. The so-called creator coin digging process is actually a block process obtained through mining machine computing power and time. The bitcoin in the new block will decrease with the increase of global computing power. So, the coins that are not owned by the creator are bitcoins that you haven't g or g out, which haven't been proced yet
2. If no one mines, there will be no computing power and no block, so bitcoin will not be proced naturally. The current situation is that with more and more people mining, more professional mining machines and more computing power, the 2100W bitcoin set will be fully mined in 2140.

2.

Take a blockchain API tool that I am currently using as an example

previously, I occasionally found bctools , which can quickly and conveniently test and verify BTC and EOS blockchain API. At the same time, these API interface test network and main network can be verified on bctools ; If you are interested, you can go http://bctools.io Use it

at present, Apis on bctools seem to have the following types:

3. No, these three are not compatible with each other and each has its own purpose
choose your own direction
the cost of developing an interface is not so high. Except for EOS, there is not much data to be chained, which is basically completed locally. As a top blockchain technology developer in China, weisanyun is still a good technology developer.

4. You think too much. Graphics card mining is based on computing power and cost. In theory, you can earn as much as you can in a day. A card can only dig a coin by day or even by month. Don't play if you don't understand. It's not something that ordinary people can play. The blackout on thunderstorm days in summer is also affected

5. Go to the official website to register an account - do a risk assessment - and you can recharge your wallet after passing the assessment. You don't need to set the address of the mine.

6. It should be the name of a currency. For example, bitcoin is BTC, and Chinese currency is BHC. I haven't heard of API. Now the most popular currency is BHC. You can find Ruide to wait and see

7. It is recommended to use currency wizard. You only need to import the read-only API to support most mainstream exchanges, which makes bookkeeping very simple and convenient. The statistical analysis of currency wizard's data is also very accurate and detailed, which can help you rece many possible wrong operations. After using it this year, you have been making profits~

8. 10 is too little. I'll give you 100

9. View plainprint?
