You can request multiple payouts per day at BetUS. Since they usually pay in 4-5 hours, you could get 15k per day. I've done it before.
Limits are lower but lines are softer. High limits, high funds security, but bet slip theft vs. lower limits, good fund security, and soft lines. Apples and oranges.
I wouldn't be complaining if clicking the 'dont accept line changes' box worked. It doesn't always work. It just happened to me a second ago even (but I saw the change before hitting confirm). Same goes for all their skins.
BOL is A+, BM/Pinn A, BetUS A-.
