I doubt the OP is going to mind being getting paid 50 BTC per week. But it's a pretty weird term, I think. I guess I can see some utility if they want to put some spending-limit policies on their cold wallet, or something like that.
I think bitcasino.io is handling this pretty terribly, though. I used to (few years ago) run bustabit, and handled many multi-million dollar wins -- and really the secret is giving issues like this absolute top priority. If a large-winner waited more than 10 minutes on me (which did happen a couple times, I admit), I considered that I failed at my job. But generally (90% of the time, I had all the funds hot and ready to go so that even a multi-million dollar win could be instantly withdrawn).
And the reason is logical, the player could've had an
amazing experience and been a raving fan-for-life, but instead they've now been given a pretty shitty/mixed experience even if the withdrawal is processed:
all very vague and not helping me calm down i have had no sleep for almost 24 hours now
I remember often I'd have players that told me they won large sums of money from other casinos that took them a week+ to pay them, and even though they won so much money (from the casino) they had such a bad/nervous/anxious experience they refuse to even come back. Kind of blows my mind that casinos are still doing it the old-school ("please nervously twiddle your thumbs while we decided what to do") way when it's so counter-productive for all parties.
