You can put this $50 on Sportingbet and clear easy bonus. 500 raked hands only, after 100 hands you get $30, after 400 another $70. Play with quarter or half buyin (just for now) in order to cut off variance, fold everything except pocket pairs and AK, camp for sets and push it. Three days like this and you are $100 richer. Then you can buyin for full or 70% and "play poker" - until you are comfy and bankrolled to move up. That was my way, and I was starting with as much as $29.

BTW, consider Aokrongly's counterplay strategy, if applied correctly it greatly reduces swings with minimal reduction of profits.

Playing 0.01-0.02 can be safer, but clearing bonus on Stars (if any) will probably take 17 years
