Firstly it’s obvious that some may think that losing a lot of money is not an actual lesson but just pain. Definitely losing money can be very difficult for some but in the grand scheme of things you will get money and you will lose money. The latter part is way worse for sure.
But if you already got at the part of losing money, then honestly no one can say anything else than it sucks. But you should look on the broader picture that the experience you will gain from the mistakes. That experience will stay and make you more mature for upcoming life.
Especially the crypto experience can be adopted to any other life situation you are facing. Maybe you will learn some things like “not investing more than you can afford” and to take profits . That’s like the basic everyone learns during their first bear run.
