What else makes online education useful?
Many things can make online education useful, one of which is that you can study remotely without having to meet everyone you need, this clearly makes it easy for yourself and also for everyone who doesn't understand the things he needs to support his work.
I think this is the best thing you can do if there is no available teacher or some people who can teach you the basics of the crypto industry. The only thing you need to have is the capability to understand what you are reading cause there are lots of resources already available on the internet. If you don't want to read, you can try to watch some of the documentaries and you still need to update yourself with some trusted social media that has all the news about what's going on in the crypto industry. In that case, education nowadays it's easy.
