Ethereum is a blockchain smart contract. Now Ethereum ranks 2-3 in the market value ranking, with a market value of 25% of bitcoin. However, Ethereum also has some problems, such as slow trading, high fuel costs and the mining mechanism that has been criticized repeatedly. Familiar? All of bitcoin's problems are with Ethereum. Some time ago, the Ethereum cloud cat game developed on Ethereum went online in the first week, directly blocking Ethereum's trading network. I tried to pay a high gas fee of nearly 100 yuan, but I still couldn't transfer it successfully. This can't help but lower my expectation of Ethereum.
