If you would like to register a character you must post your BF4 player name and platform in this forum thread then complete the character verification process.

While in game you earn game tokens for all kills, a detailed break down can be found here: Battlefield 4 Information.

The process of earning cryptos works like this:

HYPER withdrawals are sent to your HYPER Web Wallet, withdrawals requested in any other currency will be sent to the address you have set here. To prevent fraud withdrawals must be manually approved by an admin. Withdrawals are approved once every 24 hours. You can not use a Bittrex deposit address when withdrawing GoldPieces.
