Cash Games - if u can make 2bb/100 hands and play 2,000 hands a day. Then you would need to play $2/$5 stakes to make $200/day. A decent roll would be $25k min which is 50 max buyins. $50k would be more realistic with 100 max buyins. Granted 2bb/100 at 500nl is tough.

Tournies im too lazy to do the math but hmmm. Lets say u can average a 5% roi in tournies which is good imo. That's $4000 in tourney buyins a day. So lets say ur doing like 20 $200 tournies. 100 buyins would be $20k but variance and dropping down yadda yadda $25k-$50k is way safer.

So I'd say $25k-$50k would be feasible to make $200/day idk kinda rough math
