Lol, I kept laughing while reading this didnt your friends tell you that youre meant to invest what you can afford to lose? Why would you invest all you have in cryptocurrency, didnt you read about it to know the risks involved? Google is right there and you should have made some research to know exactly how it works. It is not free money and here is no guarantee you will make money, you either go broke or succeed.
I think he should learn from the mistake and realize that every investment, not just in crypto, has a big risk and we can lose all the money we have in any second. The big mistake with those people out there is they become greedy when they see the price increase so high and makes them think "Oh boy, I should buy that coin before it's higher".
So he uses his power to buy but suddenly, the price fall to deeper price, and he is angry because he makes a mistake.
