BTC has no computing power

1.

The following is the distribution chart of computing power:

the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing

however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets

2. Bitcoin and bitcoin cash (BCH) have the same mining mechanism. Miners will choose whether to dig bitcoin or bitcoin cash according to the level of mining income. It is a normal phenomenon that bitcoin computing power increases and bitcoin cash computing power decreases
in short, it is a redistribution of computing power driven by interests.

3. Of course, it is awesome to be able to get on the cloud.

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

6. Bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14
hope to adopt

7. In fact, people will not let such a thing happen, because once someone controls 51% of the computing power of the whole network, the security and non tamperability of the system will be invalid, then the decentralization system of bitcoin will collapse, and the price of bitcoin will plummet or even return to zero, which is bad news for the participants of the whole network. Therefore, we will spontaneously control the distribution of computing power in the whole network, so as not to let one company dominate. Even when many people find that the computing power of a certain mine is too large, they will take the initiative to withdraw from the mine. Now the most powerful mining pool in the whole network accounts for about 25% of the whole network.

8. I know their services. The BTC cloud computing power professional leasing service launched by easy dig provides users with a new mining method with low threshold, low cost and low risk, which is generally praised by the network

9. (1) Block time: Thor Chian Raytheon public chain blocks every 5 minutes, BTC bitcoin blocks every 10 minutes
(2) value basis: Thor chain is POW energy consumption + Odin fuel consumption, BTC is POW energy consumption
(3) miner protection mechanism: Thor chain sets Odin computing access, BTC has no miner protection mechanism
(4) mining cost: Raytheon public chain increases with computing power and Odin fuel cost, and BTC increases with computing power
(5) miner access threshold: the Odin computing power binding of Raytheon public chain decreases by 1 / 2 for every 140000 block height, and the BTC remains unchanged.

10. Because we need to ensure that the transaction records cannot be tampered with at will, if some lawbreakers want to attack bitcoin, they will pay a great price, because they must have enough computing power, which theoretically exceeds 51% of the total network computing power
