Yeah, I think that it's very risky if we buy crypto currency that is not 100 top crypto currency. I personally would buy a type of crypto currency that is only 20 and above. I judge that the crypto currency that became the number sequence of many has a little public confidence. Honestly, I am a person who is afraid to take big risks because I am not ready if I have to lose large sums of money. I am just a fighter who is still trying to finish the family economic situation for the better. My advice, you should not buy crypto currency that is not the top 100 because the crypto currency is difficult to make a profit. The crypto currency has almost no public trust so I'm afraid that the crypto currency will be extinct because it does not have a place in the market.
