That was really one of the saddest cryptocurrency related scam story I have ever heard/read, he's been partially disabled an unable to continue his work and now his savings are all gone just like that. But honestly that's very stupid, He called a fake customer support (so where did he get that fake number of exchange he used lol) and that agent asked him to provide his password and he gave it. People have to learn that they should never trust anyone and give passwords or anything that can access their personal computer, accounts, wallets especially to those people they didn't don't know. This is what will happen to those people that didn't do their assignments before investing in cryptocurrency.
