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?
It will give problems ahead of time when you regret everything in your life's decision. If the time have already passed, let it go and move on. Have some.composure and look forward what's next to come. I believe learning from them is the best way to do. The feelings of regret is destroying and we will not be able to concentrate to the things we have to do. So accept and let's wait another moment for ATH, maybe the next one is the best for you that is why you have mised the former.
