It used to bother me that
freerolls and many tournaments and S&Gs were not offered with very small amounts. Of course, I didn't know such sites as Cardschat back then and as a beginner I had to take a lot of losses.
I also don't like the payout rules on sites like
pokerstars and gg Poker at all. Depositing works smoothly while withdrawing is often a gauntlet.
