Profit taking strategies?

Been in crypto since 2018…lost my ass during 1st bull run, doubled down and averaged down, then 2nd bull run I made great gains but didn’t take any profit. What’s your strategy for profit taking???? Have a lot of anxiety (good anxiety lol) about next bull run, and I want to take profit but really not sure what is the best strategy??? Right now I have a spread sheet, 10 profit taking trades on each coin I hold. My logic is, for every 10% gain past all time highs, I pull 5% off the table. Does this make sense or am I shooting dice?!#cryptonews
