Not sure now. There are still many people who don't understand cryptocurrencies. Or the cryptocurrency that you know is incorrect. There will be a few coins in the future that are very expensive.
Cryptocurrency will succeed or should I say that it is already made its success, the right question should be "Would all the people who engage in cryptocurrency will all succeed?" I think it depends on their dedication right? because if you are just interested in the first time and suddenly you decided to stop because you have realized that cryptocurrency is so complicated, then that kind of person would not succeed in cryptocurrency for sure.
