My worst mistake was giving my money to some scheme that I hadn't even heard of.
yeah, its better not to invest anywhere that is offering big returns because the risks of turning it to a scam are really high then and theres no need to take that much risk
i think that my worst mistake was when i decided to send my money to other person as a loan without any of his details, of course he didnt return anything to me, though that was just 13 dollars
