Anonibet is catching a lot of heat and may be wrong, in this current case, to be seen, but one of the reasons they were rated so high is that in my dealings with Michael, he has been 100% honest.
One person was overpaid 15 BTC by Anonibet. When the player posted about it, Michael took full responsibility for the mistake. Michael said that the player wasn't a scammer. After that the player did pay Anonibet back. the player made a bet for 15 BTC and said if it won that he would pay back Anonibet. The bet won.
Anonibet didn't even bring the case to the forum. The player stated that he was overpaid.
Peeps. IMSO they are rated way too high. Most all the other popular bitcoin books, same as fiat currency ones, have comprehensive betting rules by sport. Anonibet has only a very small section in their terms and conditions that cover just the very basics. They offer a bonus that for all intents and purposes is like a 10% cash bonus on all deposits with only a 1X rollover. This bonus has no rules associated with it. The 1X rollover can be done at -20000 odds even. There is nothing else saying what is and what is not allowed. Yet, their only rules is they can adjust balances after the fact retroactively under their own discretion and with no explanation to remove past winnings. Some like their in-play betting platform but other sites use the exact same provider at lower margins (everything is a match just Anonibet has higher juice). Their prematch odds are also not very good. Those can be offset by bonus, but the bonus has major issues in the lack of terms followed by a catchall term.
Michael might be a great guy. Their company could want to operate fair. They however do not at least in print / policy conform to the standards of fair gambling that the oldest fiat currency books adhere to, and other bitcoin books use. It might be due to lack of experience, but that would be a concern too. I know they are the oldest for bitcoin, but some of these other books have management with decades in the sports side of the industry. I think even B- for them is too high, but could maybe swallow it. Having them rated higher than Nitrogen, Cloudbet and Casinobitco.in I don't think is wise.
BetCoin should also be no more than C or C+ and on watch imo. By watch I mean it could go either way with further adjustments from there.
