I am choosing real job because you can insure your future their and you will have a stable job that will long last. For being full time crypto, you don't know when will you gonna gain profit or you will have a big chance to have no profit.
I think you do not have to choose between the two. Full time crypto is something that doesn't require immense amount of time, it requires couple hours a day for whatever you do (depends on what you do with full time crypto) so I think you can go with both of them.
Or you can do like me who works his regular digital agency stuff but also get paid in bitcoin which means I do get paid in crypto but I also work for it, that way it is a "real job" but you also get paid in crypto for your full time work. Do you think a coffee shop that accepts bitcoin as a payment option doesn't go "real job" or "full time crypto", it is a coffee shop which is as real as it gets but also gets crypto. Work on an angle like that where you can work a real job with a skill set and also get paid in crypto as well.
