If I can get bitcoin 0.2 or 0.3 everyweek, I can do that to go full time on bitcoin and make a living with bitcoin.
Yeah .2 btc every week is not enough because in full time job you can collect a constant salary every month but in case of bitcoin, it's price fluctuate and sometime price decrease and sometime increase so you will have to face these problems if you quit your full day job for bitcoin. So don't try to do this do this as a part time and get profit from bitcoin.
i think 0.2btc per week is not easy to get it, today 0,2btc is worthed arround $120 i think no sidejob or real job will give you the salary like that except you have highest skill in your qualification.
