I started my bankroll playing freerolls. I played on Pokerstars where they gave a coupon
to the top 27 players in a freeroll that had about 1200 players. Or was it 600? Mmm, my story. Anyhow, my daughter won a ticket, and then I won one a few days later. It allowed us both to play in a $2000 weekly Saturday/Sunday tournament. We agreed to split any profits. She won like 90 cents and I won about $2.57.
These days my bankroll is over $1200 spread among 9 sites, but I have withdrawn over $1800 in 3 years. I used freerolls from many forums to start my bankrolls, and I might have 1 pokersite, Intertops that I had money on and the bankroll got to $0.
I usually do not open an account at a pokersite unless I see that they have a weekly forum tournament that is a freeroll. And I try to pay the forum back by eventually entering some of their buyin tourneys. So we help each other out.
Otherwise, I opened all my pokersites using forum links. Then the forum can earn money off me that way.
