Brother Ming said on the 28th that Ethereum has a pressure point at 3520. Generally speaking, when it reaches this position for the first time, it will drop once. It has dropped by more than 50 dollars from the highest point. Why is ETH under such great pressure at 3520? If you have any ideas, you can talk to Brother Ming! #ETH🔥🔥🔥🔥 #BTC走势分析
