I believe this to be a reliable sportsbook for 3 reasons;
1. fast deposit
2. rich market
3. tons of promotions
3. good odds
Keep it up!
I agree with you except for the 3rd one i've seen much better odds on other sportsbook. I really like the promotions being held at sportsbet.io you can't see them offered by other bitcoin sportsbook.
I don't want to reveal any tickets. I just wanted to point out the actual calculation of the leaderboards have a weakness.
I would be really happy for a statement if it is allowed to make 100 x 19 mbtc bet for the same outcome or not. If it's allowed, everybody can take advantage of it. Also if they say, they fixed the leaderboards, and the final version doesn't contains any points from multiple bets from the same selection, I believe it.
Exactly the premier leaderboards could easily be abused by high rollers just by splitting their bet amount by 19.9mbtc but there's no rules stating anything about that so maybe it's okay for now.
Edit : I came by to talk with their live support they said they don't allow this let's see what sportsbet have to say about this.
