Wild... 6 months no answers and now a 6 week fiesta in BTC talk on top of this and BC can't give the man his 750 bucks.
I'm actually facing a similar thing right now, I hadn't played in BC since my last problem with them. Today decided to log in after like 3-4 months. I still have like 280 life time refs there who sometimes play. To my surprise there was like 90 bucks of affiliate commission and I discovered they have poker now, so I tried it. Happened to take balance to like 720 ish, requested 651 usdc via erc20 and few mins later while playing dice I get kicked out and account locked.
I had few laughs around the community, no wonder most have left

this is like legit hilarious. I should be kycd long time ago and I've had this account for 5 years at least.
But what's like really weird is these winnings are from poker - meaning it's like straight from other ppl pockets, so the casino didn't lose a penny on my session, yet they are that broke that they can't pay me $651 and let me finish my $70 gambling session
