When they lose all their money due to inexperience they will call cryptocurrency a scam.

Seun Kuti's labelling of crypto people (traders) as criminals shows that he doesn't know anything about crypto trading. If he knew that cryptocurrencies are volatile he wouldn't be blaming innocent traders for his sister's lose of 50 million naira in trading, according to him.
People that are looking for where to make quick money should understand that crypto trading is not a shortcut to riches. It is a risky business that people don't need to rush into because they have heard that others are making easy money from it.
