I think about all the people that sold BTC when it peaked at $27k or something like that and in the next 8 months or so it slipped to nearly $2k. The people who panic sold during that time have a lot of regrets today, that's for sure.

I also know people that thought it would be a good idea to get involved when the meteoric rise to $60k or whatever it was, was going on. They have a lot of regrets as well. As a HODLer, I never suffer these things but who knows what the future holds!
