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?
Doesn't make sense if you sell at peak and then wait for the price to go lower again and re-invest. Why not just go long term, and see how long you can hold and wait for at least 2 bull runs before you sell your coin to maximize your profit?
At least with this strategy you don't need to time the market during it's first bull run. I know it's going to be tempting to sell, but it's hard to time the market as well. That's why it's really better just to hold on our coins for a long time.
