Yes it is possible but i think the risk is high. The industry is volatile , risky and changes from time time. I would suggest not to abandon or totally abandon your permanent work say if you have office works that gives you stable income. Maybe or think again if you are earning amount of money is already enough for your needs if it is not, then dont quit the regular job.

Yes it's nice to earn enough bitcoin specially when you don't have a regular job, in fact I am one of those who earn bitcoin even they don't have job because you only need capital here so you can start trading bitcoin or by just using your internet connection you can work here at the forum and earn a lot of bitcoin over time.

I also think that without trading bitcoin it is not possible to earn sufficient money. but many expenses may be managed through bitcoin work like review, adds etc. So one should be always in touch with bitcoin platform so that may be involve in trading also.  

Yes it is possible but will I suggest doing it instead of a real job? Then no. Yes I know earning Bitcoin online is possible in many ways but the one thing I am concerned the most is its volatility and making a volatile currency as your main income can cause you a lot of problems because your buying power will be different from each period you might by lesser items compared to last week and you might buy more compared to other weeks.if you are looking for sustainability than you might need to find a job paying with fiat currency.

I was just wondering that is it possible to earn steady income without going 8-5 hours regular office job..
I mean you got some bitcoin in your wallet .. are you the enough for living ?
another option is to regularly working on Bitcoin related trading/.. that's it for the time being to alive without job.

Yes, In bitcoin you can do earn enough money.this do earn money you find out big volume and invest your bitcoin.

If I ever reach that state, where I am earning enough Bitcoins to live of, I would not quit my job.
Sure, having the whole day for your self and to do whatever you want sound fun, but it could be boring after some time.

I would agree with my employer on a part-time contract, 3 working days a week or something like that - just to keep my feet on the ground and maintain social contact

Right now I don’t have a job and my only means of income is joining signature campaign, the rate for my rank is already big if i convert it in our currency its already the same as a regular employee with a basic pay here in my country. I can say that what I am getting from here is just enough to pay bills a little bit of savings and a food in my plate.

Try to trade. many people are now getting money because of the trading. try and you can earn many bitcoins.
