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?
indeed there is a little regret i didn't sell at ATH last time, i kept thinking if only at that time i sold my bitcoin then now i can buy it back and my bitcoin becomes double. but that's all in the past, all i can do right now is buy slowly when the market dips now.
