Well it depends upon how much deep you understand about the crypto market and the future opportunities in it so that you could quit your job and indulge all the time in the crypto market.There is no doubt that bitcoin market has a very big potential of earning but that doesn't mean that everyone entering it would succeed easily.Here self motivation and dedication is needed to earn otherwise continuing with the regular job itself is better
Real job gives you security and stability when it comes to your finacial needs. And even though full time cryptocurrencies isn't that stable it could give you much profit than your real job. But what's the point of choosing if you can do both.
Full time crypto sounds scarry to me. If you're a perfect trader, you can avoid your regular job and start full time job in crypto. Only 1% of the traders can do this I think. The rest will keep working in their regular jobs.
