Do take note that if you wish to request your payout from bux.to to be credited to this card, you need at least a min us$75, unlike normal payout which is just us$10 to your alertpay account.
And seems like you have to load funds through their co-brand card partner website:
Payoneer uses MasterCard prepaid cards to enable payouts from websites to individuals worldwide.
MOST IMPORTANT THING: You must upgrade your Bux.to account and become a premium member!
