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 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. in-depth analysis still needs to be done so as not to buy the wrong coin when the market dip.
There's no room for regrets in crypto, as you still have more chances to sell when bitcoin reaches new ATH. But if i were you, learn to set a target selling price because that will be your guide when to sell and make profits, and then just buy back again when the market creates another correction.
"Focusing too much on a lost opportunity can be like carrying around a weight," muses Blair Thomas, co-founder of eMerchantBroker. "When I have carried around too many regrets, it has impacted my ability to see new ventures." Source:
