I greatly prefer going full-time on crypt-currencies because there is something you forgot to mention it is that pay is much higher than with a regular job !
Not necessarily, someone living in the first world can earn a great deal of money if he has a good job, the pay in crypto can be incredible as well but the set of skills needed do not overlap much, the only ones that can earn a fortune with bitcoin and fiat with the same skill set are programmers and traders, everyone else will need to adjust and change the way they do things or learn completely new skills.
