That's why I stick with my locals, & only bookmaker or pinnacle (when they allowed US players)
Only the long time proven books are worth putting your money into, & if you hit them for $60,000 on a 10 team parlay, they won't stiff you.
I know there are other books others play on, but I only trust very few.
I'm lucky. I don't even go the casino anymore. My money's spread out over a few apps, and getting paid is easier than going to the bank to make a with drawl. Plus I'm getting comped by a few and never leaving my house.
