Blockchain is free of regulations and borders, there is no technical possibility to BAN crypto (unless you want to shutdown internet). Your funds will remain yours.

I do believe this course is a bit old and is free, I've looked some parts of it way back. Dunno maybe they have added few videos now but it is imformative well enough and I do believe if you watch all videos newbies can learn a lot about cryptocurrency in general. Very imformative, at least parts I've watched

If you are interested about blockchain tech and way how business are seeing to make centralzied ones you can also check these courses:

Although I found them not entertaining enough since I mostly know what they are talking about, but courses are free and can be good start
