I would say mastering the exit strategy means NO EXIT.
Why exit the better working money and fall back into the FIAT simulation?
Once you exit the FIAT system, you never want to get back in.
Exactly!
When you're thinking like OP trying to turn bitcoin back to fiat so that you don't end up "holding the bag" you still don't get what bitcoin is.
Personally, I don't take profit in literal sense. I'm in profit all the time. I've been in profit since 2017 because I bought during the 2016 bear market so 6 months later bitcoin crossed the $1k level and never came back to it, so I could've taken profit at any point. 2017, 18, 19, at 5k, 10k, 20k, but what would be the point? Every year with bitcoin seems to be a productive year.
Nowadays I only spend at new highs. I don't take profit, I give myself a part on the back and tell myself, good job, here's a new toy to play with. Sometimes it's a new computer, sometimes a new car, but I know I'm going to hold my bitcoin for many years. Nothing even compares to it. I'd rather have bitcoin than gold or real estate.
