In addition to Cryptoback™ rewards, the Wirex X-tras programme also pays users a bonus on their WXT balance. This means that those who wish to HODL WXT can enjoy a monthly Savings Bonus payment on top of any price gains. The Savings Bonus pays up to 16% AER, based on users’ monthly WXT holdings. The bonus percentage is dictated by users’ membership plans. The bonus is paid in WXT and added to the user’s overall balance, which continues to earn up to 16% AER.
