I honestly think Rollbit is illiquid or something haha.

A guy I knew bet a few thousand on a soccer match and was literally accused of rigging the game. They would not pay him until days later and he had to literally explain why he placed the bet on a conference call with the owners. His reply was he was gambling lol

They own a sportsbook... they let people bet on sports... a lot of times they will be weird and throw a fuss. They are very dodgy but they usually do end up paying... but you have to put up a fight for no reason. I'm assuming some people just don't put up that fight, I wouldn't use them.
