In my strategy of accumulating more after selling during the bull market, I suggested to myself that I sell to fait (USDT) rather than a stable coin. Although USDT may also be centralized, I think it's more safe than some other stable altcoins. Such a strategy is good, but not everyone likes to adopt it. Some people will prefer to hold their coins for so many years before they sell off. For example, a member said that he has been holding his bitcoin for more than 10 years, and for those intervals, two bull markets have been crossed.
