I think that everyone who has been in the crypto industry for a long time has made some minor or major mistakes. I made the most mistaken investments at the end of "the golden age of the ICO", at the turn of 2017/2018, when, encouraged by past profits, I invested dozens of ETH in projects that turned out to be total mistakes. The main thing is not to break down, but to learn from mistakes.
I also support your point, there are such moments. of course, it is easy to judge after some time and already knowing how it ended. but if you look at the time, it was the right investment, the only mistake is that I did not make a fixation of funds, of course, out of greed and belief in value.
