For anyone who is stuck not able to withdraw winnings because they haven't verified their CoinPoker cashier account, here is a step by step:
1. You have to have an ERC20 compatible Ethereum wallet. This means that you can send various tokens to your ethereum wallet, including CHP. MyEtherWallet is a good web based ERC20 compatible ETH wallet.
Go to
https://www.myetherwallet.com/
Create a new wallet.
Save your Private Key. Never give your private key to anyone!
2. Have someone transfer a small amount of CHP to your wallet. Give them your public address, not your private one!
3. After you've received the CHP, you need to add the custom token on your ETH wallet. You already have the token but you aren't able to send or receive it until you add it.
Click on the "Add custom token" button and enter the following values:
Token Contract Address: 0xf3db7560e820834658b590c96234c333cd3d5e5e
Token Symbol: CHP
Decimals: 18
4. Now that you've added CHP to your MyEtherWallet, you are able to send a small amount to the CoinPoker cashier to verify your account.
Go to the CoinPoker cashier in the client. There will be a message there telling you exactly how much CHP to send to the cashier and the ETH address to send it to. Also, make sure you set the gas limit they ask you to(I think it is 60,000).
5. Now you are verified! You should be able to withdraw CHP from the CoinPoker cashier to your MyEtherWallet.
I'm happy to help if anyone needs it.
