If it gives a good assurance for a good source of income then why not, but as of you know bitcoin after a stable job then as should say that maybe bitcoin is a part of mysideline job .But if in long run if it gives you more than your stable job, then maybe I will stay focus on bitcoin and quit for my day job.
if you can get salary from both of them why not?
i think we can use bitcoin as assurance investment for retirement day, then use real salary from daily cost and needs.
Yeah for investment in bitcoin you do not have to quit your day job. if only to buy and hold for the long term. but if you are a trader, you might have to take the full time for bitcoin. I see a lot of people who took full time in bitcoin and just to be a trader. because being a trader can benefit very high, even more than someone who real job.
