Maybe that in the future it will become possible but at the moment I do not see it happening.
Yeah price is not higher at a moment and it will be risky to get full time in bitcoins as price may fall down in coming future and that can affect our life financially.
This is why I wouldn't go full time. If the price stalls there's not much you can do.
And then you won't have any money without a stable job. Stable job gives you security and also still gives time (depending on what job) to invest and research bitcoin. So i think the full time job option is better then full time bitcoin for these reasons.
