In my opinion, there was nothing to take a lesson, these are the factors affecting the market and any person could not predict this. It is very normal for people to experience financial losses on this scale, but they have the chance to recover these losses in the future by making more proper and wise investments.
With so many happenings in 2022, it was one of the worst years for bitcoin and the crypto market, and you didn't learn anything there? I really didn't expect it, and you think it's normal, including the FTX incident? which even hurt users and lost the trust of most people to keep investing in the bitcoin and crypto market.
What I learned there is that most people worship and use centralized exchanges which in the end are scammers who steal your money, the importance of reading, the importance of analyzing an exchange that will be used as a tool for your crypto exchange and save. And most Altcoins may be potentially bad like FTX or Luna, so be careful. and in 2022 strengthen my view that Bitcoin is indeed the only one I must buy.
