Of course, most of us probably regret not investing more of our money in bitcoin in March last year, when its price was about ten times lower than the current one.

Almost all of us make mistakes, and we all have lost profits. It's impossible to predict everything in this market. You need to draw certain conclusions from your new experience and move on.
