But alot of people do take those large risks where its all or nothing, make an all or nothing risk where if they can pull it off, it is a huge reward but if not, they will loose everything. It is possible, PKR is a new site, with a new system. There could easily be a flaw somewhere people are missing because it is new.
Im not saying PKR is rigged, but would most definately agree there is more bad beats etc on there than most other sites. Luck seems to come in 'streaks' but more than often, its bad ones.
