I give betcoin sports a 5.
Honestly not sure why they are so low, they have more games than direct bet, same number as nitrogen, and 3 times as many lines to take on football than anyone...
You can take a line 3 full points either way on football. Nitrogen I can only find 1.
Direct bet has no good games and very few bets. Betcoin has every college and pro football game.
