I could not play at a casino, that if I hit a 100x bet win, that's my max draw out for the day.
Your 750X (which is not big in terms of your bet) a week to withdraw, Madness.
Usually, a couple years ago if I told people about online casinos I would usually get asked how I could be sure the games were fair or casinos would pay out. I'd usually tell people that you go go based on reputation, look at reviews, etc and you would *probably* be getting a fair game. Most people weren't particularly convinced.
These days, I simply just tell people it's probably not worth playing at all, to stick with land-based (well, they're all shut down now I guess), and this sort of thing is why. Waiting almost a week for a withdrawal with daily, weekly, monthly limits on withdrawals if you manage to hit big is standard practice. Sometimes it's even longer than a week. I deal with it myself but I wouldn't want to put others through the experience (though I've cut back a ton as well).
Oh, and that 20k win could easily be 2-3 months to cashout at many... even most US casinos, though I don't know what brango's policies are exactly, if they'll pay out more than whatever their weekly limit is.
This is what it's like with online gambling in the USA (at least the unregulated sites, don't know what the regulated experience is like in those 3 or 4 states). So when choosing a casino, having to decide between a casino that gives you a decent chance of winning or a casino that will pay you in a reasonable time is a real decision you may have to make.
I think it can be difficult for people from some other parts of the world to understand that we don't really have any options that come without one kind of flaw or another. If I had to recommend a single casino to someone it would probably be bovada (bodog), though they are not without flaws either. They usually pay within 24 hours if you don't take a bonus and I think their default withdrawal limit is like $9k, though maybe that requires some VIP status.
Edit: Funny posted this right after labeled did, but yeah it all kind of sucks over here, in terms of online gambling.
