I never wake up asking myself if I should or will take profits today.
I almost always wake up thinking "DID I take profits while I slept"...
Back when bitcoin was doing nothing, I sat down and made a spreadsheet detailing exactly at what price and how much I'd sell for, and at what price points I should follow up and buy the dips. Doing this back then allowed me to take my time on making the decisions, and do so without having emotions drive the decisions.
Now, I just follow the plan.. Its much less stressful, and so far, previous me seems to have made the correct decisions..
So.. my advice is:
make a plan
follow the plan
and most importantly, keep emotions out of it...
