Can't believe a thread like is maintained for almost 9 years.  I have a few things to say though,

1- I don't know stake is given "B" when they have the biggest limits in sports betting and even influencers like Drake who bet on NBA there.

2- Sportsbet.io should be "B" instead of "C" according to me because they have a nice spotsbook with lots of bonuses and promotions.

Bitsler has improved a lot lately and even introduced cash-outs on betting so maybe they can be upgraded to "B".
