currently it provides me with much more income than what i earn with bitcoin.
I know some people that did commit soley to bitcoin, but sadly it didn't work out for all of them, and some now have huge loans (mostly those who invested in bitcoin mining operation) and
have no good source off income to return it.
One day in the future i believe there will be enough space and wealth bitcoin related, and many will find their place in bitcoin related service or jobs, but for now, it's best
to leave it as a side job, and additional source of income (or better yet just save it on the side, because we all know that bitcoin will either thrive one day)
No I don't think so, if you conduct a survey then you will find that majority of users will never prefer to quit their jobs for bitcoin and they they will be comfortable in keeping bitcoin as a part time income.
