As the saying goes, 'the one who knows how to buy is just an apprentice, while the one who knows how to sell is the master.' Now let's talk about selling coins.

Many people who speculate on cryptocurrency always think about selling at the highest point, but to be honest, you only know that highest point after the fact.

I think there are two relatively reliable selling methods. One is the target profit-taking method, which means setting a profit target for yourself, or identifying a certain price, placing an order in advance, and selling when it reaches, without being greedy.

Another method is technical analysis, such as looking at MACD and Candlestick Chart. When the 5-day moving average crosses below the 7-day moving average and MACD's DIF line crosses below DEA, it could be a signal of a major decline. Taking ETH as an example, this theory has been quite accurate in predicting several major declines in the past.
