mBet.io is the only 'normal' Bitcoin sportsbook with horse racing I believe. Fairlay is a betting exchange that also offers horse racing.

I was bet in mbet.io but now I dont like this racebook. Im searching alternatives.

Thanks guys!

Nitrogen has some of the worst odds available.
How can you rate them an A+

Oh ok.   
So by that notion, your grading is reflected strictly based on NFL odds?
Am I understanding that correctly?

Anyone know what happened to Anonibet? Their promotions seemed pretty good and I was thinking of depositing, but their forum account hasn't logged on since July, hasn't posted since June 2017, and their thread seems to be filled with complaints.

Peeps, have you used or know anyone who has used Anonibet recently?

The criteria used for ratings includes odds, limits, payout times, customer service, poster input,  KYC, markets offered, promotions/contests, time in business and any past problems.

@Peeps Place. Did 1xbit pay its users that claimed that they were not paid by the site? I know that it destroyed its reputation for some accusations that we might not be able to prove if they are true or not. But I reckon giving them a D is giving them too much acknowledgement.

Everyone will have a different rating depending upon their needs. I feel very confident in having Nitrogen, Betcoin and Bitcoinrush as the top 3 books ahead of the rest. All three have an "A" rating. All three books have been great as far as communication. If any problems occur, all three will respond very fast.

Nitrogen is the top book. They dwarf other books as far as size and employees. Their payout time has been 5-15 minutes with recent withdrawals. Bitcoinrush has the best odds of all books listed in the ratings guide followed by Nitrogen. The price is normally a penny different in the NFL.

Using today's game as a comparison. Bitcoinrush has Indianapolis +10.5 -103 (1.93) while Nitrogen has Indianapolis +10.5 -104 (1.921). There's also a penny difference if you were to take the other side New England. The standard, non-reduced shops, is -110 (1.91). Nitrogen has high limits, 4.2 BTC for the NFL game tonight.

Since Betcoin is receiving the most criticism, I'll go into their advantages. Betcoin has the most markets of all of the books by a good margin. For the most part their live betting is up continuously. Many books only have live betting available during commercial breaks. Using last night's baseball game, because that is the the game that I was following, Betcoin had 88 live markets available during the Oakland/NYY baseball game. Some books just put up a side and total during commercial breaks. Payouts at Betcoin are taking 5-15 minutes.

I'm not comfortable playing there because of confiscated funds by their sister site 1xbet. The other thing that bothered me is that they have two sets of lines. I'm not sure if the line change is due to the amount of winnings or sharp action in general. There's a substantial difference in house take.
