Once it hits your blockchain wallet 24 to 48 hours later then move it back to coinbase into your bank account and boom it's there.
To withdraw? Hit withdraw in your poker client and go to you blockchain wallet and copy that address put it the address section on your poker client and amount you want to withdraw. Goto you blockchain wallet and send it to the spit wallet and voila. Tell the client what you deposit and it will spit out a bitcoin address to send it to. Buy you bitcoin > get a wallet send your bitcoin there. Yeah bitcoin is volatile but if you deposit to bitcoin straight to a site and play and then withdraw? What's it matter? The volatility is whether you are winning player. It's been around for a bit and don't see bitcoin tanking overnight. Yeah it's an extra step but we are getting our withdrawals in days not weeks and sometimes you wake up in the morning and our withdraw hits? Many of the sites would prefer bitcoin over credit cards and will not charge you anything for a bitcoin deposit/withdrawal. Being a US poker player and hadn't gotten into bitcoin yet? Whaaaaa? It's not hard.
