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.
The biggest mistake which people make in crypto is that do not buy when the market is Red and coins prices are low. When they see that coin prices are rising then they jump in the train which is only because of fear of missing out. Most of the time, they enter at the very top and once they entered, the big whales have already starting exiting the market. So those who enter in FOMO usually lose their money in this trade.
