Reflection: At the end of the last bull market, my Ethereum was often put into the machine gun pool to earn an annual interest of 15 points for fifteen days. As a result, I missed the high point of selling at 4,000, and finally cleared the position at only 3,000. Ethereum. In the bull market, high prices often only last for a few days. It is better to invest in current financial management of cryptocurrency assets.

And you need to set aside some funds in advance to buy the bottom of the bear market. You can also consider shorting a small part of the funds with two or three times leverage (of course, shorting is more difficult), and you can do U-based contracts.
