I see 1.02-1.04 everywhere. Where did you get the odds from
I am pretty sure the odds in the OP is wrong.
It is around 1.02 to 1.05 for 3/5 of the listed picks.
Hi, the Odds were from https://nitrogensports.eu/ at about 5:00 to 5:30 PM 23 January forum time. These odds are generally the highest in bitcoin betting sites.
I guessed as much. The bet is you mentioned in OP is different from the bet you made.
The bet you mentioned in the OP is Novak Djokovic vs Gilles Simon : Novak Djokovic Odds about 1.04-1.05
The bet you placed is Novak Djokovic (-2.5 Sets) (If there were 3 or more sets played, the bet loses even if he wins or something like that. I don't bet at Tennis)
No sportsbooks cannot give odds that high for such low risk games, because anyone can do arbitrage and make a nice amount with zero risk.
In his bet he has chosen Djokovic to win with +3 sets, meaning if dojokovic wins 3-0 he will win that bet but if Simon by any chance wins a set then he will lose that bet.
