I believe cryptocurrency is an opportunity. If you have enough knowledge about crypto and you can control it then you can earn enough money from crypto. But if you do not have enough knowledge about the crypto market when you join in it, I think it will be very risky for you.
Indeed when we already has the necessary knowledge about cryptocurrency, that is a big chance for us to know how to maximize the possibilities that we could get from it including making some profit from it. But for everyone who still learning or everyone who still don't get to know about cryptocurrency will find it intimidating to try to enter in this cryptocurrenc world.
