It is possible, but only if you have the necessary skills. But I don't recommend you completely abandon official work. No one knows what will happen with bitcoin in the future. You risk to remain without money and pensions. You will agree with me it is very risky.
I agree with you dude. We can't always rely our financial status on bitcoins or other crytocurrency . Someday bitcoin will fall (I hope this will not happen ) and you will have to work again. While early we must invest our money or btc on bussiness .
