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.
I full agree with you, even not earning a salary from bitcoin im able to get some income, with those im planing to fund my savings, starting on the next year, as this year im investing almost everything i got. But i wouldnt never left my job, as those will affect me if im thinking to retire, even with some good ammount of bitcoin, i would just save the bitcoin into the bank or make some aplications as i consider almost all ways to get bitcoins very risk to even try it again.
