Create BitCoin address for each registered user I am working on a PokerGame where I need to implement BitCoins. For each registered user, I need a unique bitcoin address generated, toward which they can make payments and I make them show it when they access their game account. How can implement this? I am using Java.

Thanks
You will want to look into this implementation of bitcoin.

https://bitcoinj.github.io/

The documentation will provide all required information for generating bitcoin addresses.

It is generally unwise to reuse addresses, also very expensive to be constantly moving small amounts on the main chain. You may want to consider other implementation options rather than one address per user.
