Why regretting when you still have the opportunity? I meant you wished to have invested in bitcoin when it was @at $40000. All I can say is that you can wait till next bear market, let the price of bitcoin fall and invest around $50000. I may be wrong that bitcoin can get to $50000 but I think it is worth trying. Also you do not need to regret of thatwhat you supposed not to regret.
