Have no regrets, you only live once and life is too short to worry. If you don't know anything like that, hold bitcoin and chill. Again, life is too short not to hold any bitcoin and regret later when it's back above 100k.
Thanks for the reminder, the key word here is to hold and chill, yes, perhaps you can also buy because it's at a discount, buy as much as you can if you don't want to do DCA. And after that if the market recovered to somewhat like in the $90k-$95k, then relax.
As it could be the time that the market is going to bounce back. And if that happens, the price could be in the 6 digits before we all know and then that is instant profit again and we (and you), can go back and just sit back and chill and see your wallet grows.
