Zero and Ethereum
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
although bitcoin and Ethernet are both digital currencies, unlike bitcoin, the main purpose of Ethernet is not to build itself as a payment substitute, but to facilitate and monetize the operation of Ethereum, so that developers can build and run distributed applications
if you don't have a lot of spare money on hand, it's a good choice to invest in virtual currency at this time. With a threshold of several hundred yuan, new users of the realm can also get a $50 coupon, which will not affect our lives, but also bring considerable benefits<
the investment mode that can also trade is not only suitable for young people, but also for the elderly, because it does not require you to have much deep investment experience, as long as you know how to judge the direction of price rise and fall, and the trading time is relatively free, 24 hours a day can be operated at any time.
Ethereum is the main network, and Ethereum is the currency in it (my home), but now it is basically called Ethereum or eth or Ethereum, and it is rarely called Ethereum (we do). Coin an is a digital asset exchange, in which trading needs to transfer the currency to their platform wallet for operation (other people's home)
about realization: ether belongs to the mainstream currency. Realization is no problem, at least it will not run away. The rise and fall of this kind of virtual assets is still quite large. If you are not keen on finance, you should be prepared for loss. If you want to invest, you should be cautious
