Why was it a nightmare? How long did it eventually take?
Took a week or so to get ironed out, but then I discovered that they had ludicrously low annual cashout limits, so stopped using them entirely, in favor of Gemini.
They probably changed it afterwards, it is now much higher for pro level (daily $10mil), with a strange exception for Texas (TX is only up to 200K daily or something like that).
I have no idea why, maybe their bank has a quirk.
