It's a simple answers: your money your choice. If you are going to this market with your greedy and lack of understanding, you will lost all your money. And noway to get back your money 
Yeah, I agree with you bro, I have known people who lose a huge amount of money because they're greedy to earn huge money in a short period of time. People who not fully prepared or not ready to engage in cryptocurrency will surely lose money. Once you lose everything, there is no chance to bring back you 100% investment. I'm always telling to those people who want to invest in cryptocurrency market they should study first or do some research in especially in trading because of high risk.
