That is very sad and why I have not invested anything I cannot afford to lose and if the value of my crypto sky rocketed and then dropped I wouldn't see it as losing alot of money as I never actually had that sum in the first place
Even though you invested more money than you can afford to lose then you still need to understand and study the risks of your investment because i think that he did suicide because of the losses that he cannot accept and that is why it is best to study about it first and do a lot of research before putting any money into virtual currencies.
