Hi bellbroken...Yes, most casinos that allow bitcoin deposits will allow bitcoin withdrawals back to your wallet. Your best bet is to use a standalone wallet like Electrum. If you use Circle/Coinbase, they are essentially providing banking services and do not like you to use bitcoin for online gaming. Stay away from exchanges and you should be fine. Also, for $10 you can order a bitpay debit card that allows you to transfer all your bitcoin balance to a visa. You can do ATM withdrawals and shop, like you would with any other debit card. BTW, that's how I was paid from Posh. They want to send you a check. But if you push them hard and let them know that you don't have a checking account etc and are having issues, they can send your payment via bitcoin. Bitcoin Payment literally takes 30 seconds. Hope this helps.
