How do you get bitcoin to bank account??
In the US, I would suggest Coinbase. PayPal I believe also supports buying and selling crypto and transferring to and from wallets. They only used to allow buying and selling, not transferring, but I believe that's changed if you provide verification.
But Coinbase is the easiest and the largest crypto exchange, and in my experience the easiest to get verified with.
You should be keeping your crypto on a wallet you own (I use Exodus on PC and Android). Do not leave crypto in the hands of a casino or an exchange like Coinbase for any longer than necessary: withdraw to Exodus every time you are done playing for the day, and withdraw to Exodus after buying crypto. History tells us this is what you want to do: once-trusted exchanges like Mt.Gox, Bitfloor, FTX, and many others over the years have suddenly gone belly-up and absconded with crypto funds. Coinbase has lasted the longest, I think, out of all the majors, but you should still be cautious.
I recommend NOT transferring crypto directly from Coinbase to a gambling site: they have closed accounts because of this. Buy the crypto, transfer it to your wallet (e.g. Exodus), THEN transfer from your wallet to the casino. Same thing when you win in the reverse: withdraw crypto from casino to your own wallet, then transfer crypto to Coinbase when you are ready to sell it and cash out.
When you are ready to cash out, send your crypto to Coinbase, sell it for cash, then withdraw to bank or debit card or PayPal. Normal bank withdrawals are free and clear in 1-3 business days. In my personal experience, it's faster: if I withdraw at 1am on Monday, it's in my bank account by noon. If you need the money instantly, you'll pay a nominal fee to withdraw instantly to PayPal, debit card, or instant ACH-supporting bank account.
I do not play anywhere without crypto anymore as an American: I don't see the point in 2025 of putting up with delays for withdrawals, weekly withdrawal caps, expensive withdrawal fees, sketchy fiat e-wallets, or risky paper checks that seem to bounce fairly often these days.
With crypto, withdrawals can (and should) be instant after completing whatever KYC verification, if any, your casino requires. With Bitcoin it's instant, but you will need to wait about 2 hours for the necessary confirmations. Other crypto coins like Ripple (XRP) and Ethereum (ETH) take much less time to confirm and are, for all intents and purposes, genuinely instant.
