Now Ethereum computing power

1. According to the data of spider mine pool:
BTC full network computing power 153.280eh/s, mining difficulty 21.72t, current block height 672055, theoretical income 0.00000690/t/day
the total network computing power of eth is 418.403th/s, the mining difficulty is 5380.94t, the current block height is 11923460, and the theoretical profit is 0.00709464/100mh/day
BSV network computing power is 0.544eh/s, mining difficulty is 0.08t, current block height is 675889, and theoretical income is 0.0081/t/day
BCH's whole network computing power is 1.596eh/s, mining difficulty is 0.20, the current block height is 676209, and the theoretical profit is 0.00056395/t/day<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

2. Rx470 and rx570 are the most cost-effective ones (before 1500), and their mining performance is no worse than 480 and 580, but they are much cheaper. We can also consider the lower 460 and 560, and other models are not worth considering.

3. It's better not to exceed 1100 cores. In fact, 1050 cores are just a little bit more than 1100 cores. Because even if you go up, it won't be obvious. The card game is still the card. Don't exceed the video memory. The core performance of 370 is only average at present. Bandwidth is not the bottleneck. In fact, it's just a little bit more psychological comfort

bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

5. If you want to make profits online, you still have to look at the risk of fire. If you are optimistic about the risk, you can do it again. Don't take the risk to do it.

6. Resolution:
under normal circumstances
1G=1000M
1GH=1000MH
1gh=1000mh

7. There are three types: application type, payment type and security type. Most of them are applied tokens. Singapore has other regulatory policies for securities and payment.
