In fact, everything is clear, there are six offices that more or less pay, what you put in the lower rating does not have any significance. Perhaps I will try the C+, C rating when the seasons start. But for example, I wrote about the same Trustdice, I funded my account and it turned out that the sportsbook they do not work (although the site and advertising and odds are there), and they forced them to rollover in the casino. Of course I lost a lot of money. Anonibet is also rubbish which cancelled winning bets and took 10% for withdrawal.
Agree that the top 6 is really all that's needed since they do pay. I did lower the Anonibet rating based on your experience. Why did Trustdice make you rollover in the casino? Was it due to a bonus?
Personally for me A offices do not exist as they do not accept users from my country. Sportsbet.io can probably still be raised, although you know better (they must be reliable, being sponsors of such big teams). I'm pretty sure I didn't take the bonus if they had it (I try not to take bonuses), but even if I did take it, it was for sportsbook, and since sportsbook didn't work it's not right to send me to unscrew it. Although all so likely it was just a rollover for withdrawal (I wanted to withdraw at once having learnt that sportsbook does not work, and they did not let me do it).
It's probably written in my post history about the Trustdice situation, if it's that important to you you can look it up.
