Just go with the flow is my advice to you. You should not be scared, they can't punish millions of people for doing crypto if it was illegal. But it is not illegal so no worries there. If some country pronounces it illegal just switch to another country after a while. You are missing the chance of earning money and learning about new technology at the same time.
As the matter of fact, it will be a new payment (financial) system in our near future.
