Speaking about sportsbet lovers,
BK8 has a subreddit where a lot of predictions/tipsters share their knowledge there. Last time I notice the prediction was quite accurate. For example, Granada vs Villarreal, Elche vs Rayo Vallecano, a user even predicted the goal difference, and the first half draw thing. And then, Amir Khan vs Kell Brook where a user predicted TKO but on round 7 (not 6)... that's so close!
Disclaimer: it might be a coincidence (luck), so don't blindly trust the tipsters.
