It all depends on them because if they are honest they will not blame crypto and will admit it is their fault. Because I believe that as a crypto investor, everyone is very familiar with the saying “not your keys, not your coins”. If they adhere to this, never trust any third party and they will never fall into such a heartbreaking situation . Only selfish people blame crypto when it's their fault.
As I see it, many people were victims of Mt.gox and it's been 10 years but they are still bitcoin investors, they haven't left the market or blamed the market as you think . Not everyone is selfish, not everyone has negative thoughts or gives up early just because of a few failures.
