One important thing to understand here is that Pinnacle is the sharpest bookmaker in the world, and Rollbit's provider is copying their odds.

Here is the timeline:
1. OP bets on Rollbit first (The whole market is at 2.1)
2. OP max bets twice on Pinnacle and MOVES the whole market to 1.9x (Because everybody is copying Pinnacle, as I said before)
3. After the game Rollbits provider checks Pinnacles closing line(1.9x) and "believes" that the original 2.1 was mispriced.


Next, let's compare the odds using BetsApi:

Nitrogen 2.01 06/24 06:35

So at the time when OP placed this bet, Nitrogensports had even higher odds than Rollbit.



From a perspective of a professional sports bettor this looks like a blatant freeroll/scam.
