Why can't bitcoin dig

1. mining is actually competing for the right to pack in the block
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.

2. Ordinary computer mining has long been unworkable. If it was OK two years ago, at present, the common CPU mining clients have been canceled. Now mining needs professional ASIC miner
mining is a 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.

3. The concept of smart contract can be summarized as:
a piece of code
(smart contract), which is deployed on the shared and copied
ledger
to maintain its own state, control its own assets and respond to the received
external information
or assets. Smart contract, in short, is a set of commitments defined in digital form, including agreements on which contract participants can implement these commitments.

Recently, Tencent Yujian Threat Intelligence Center has detected that Lazarus, a suspected hacker organization in North Korea, is active again. It frequently attacks by using the latest Flash vulnerability cve-2018-4878. It attacks mainly foreign digital currency exchanges by spreading malicious DOC documents that hide fallchill remote control Trojan horse

After analyzing and tracing the source, Tencent security anti-virus laboratory found that the load unloaded by the malicious document is the latest variant of fallchill remote control Trojan horse. Fallchill trojan is a Trojan developed and used by Lazarus, a hacker organization in North Korea. It first appeared in early 2017. The Trojan can realize remote file operation, remote process operation, remote information acquisition, self unloading and other functions. Once the user is recruited, the important computer information will face great threat

6. Bitcoin is now issued less and less, because it is too expensive to be so easy for you to dig.

7. According to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, it is an ideal state that the "proction time of each block is 10 minutes" used in the above calculation method, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error.

8. Bitcoin is more and more difficult to dig in the future. Now ordinary computers can't dig a coin a year, so it's very difficult to dig out. In fact, it doesn't matter how much bitcoin has not been g. The minimum unit of bitcoin can be one in 100 million, so there's no need to worry about the quantity.

9. Bitcoin used to be very good at "digging", which could be completed by ordinary computer CPU, and it could automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it.
