It often become a good opportunity when you sell at a peak and after that the correction come and you buy again with low price but many people miss that opportunity who then regret but I do not regret when I miss that opportunity because I do not do greed and remain satisfied with my current amount of coins and I know in the future the price will grow again to another ATH and my current coins are enough to give me enough profit. With this thought I keep myself tension free.
What is your views and conditions at that time?
I keep hearing people saying "clean up your portfolio and throw out the trash before the next bull market". I think that advice is incorrect. Low cap coins that lose the most money during a bear market, like 0xMR and TRI for example, will pump the most during a bull market. Do not sell low and buy high. And remember that you can't time the market so don't be too hard on yourself. You do need to take profits though so one thing I do is to sell my NEAR and ICP staking rewards and yield farming rewards monthly. This way I always have income.
