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?
There is not stop to ATH sometimes if the coin or token is bullish, every trader or investor must have a price target that's the only way they will escape getting rekt when you reach your target make sure you take your profit, if the ATH continues it's all good at least you made some profit.
