Availability can depend on your account and environment. If Add Funds is unavailable, contact support. G2U checks supported minimums before creating the invoice; a coin selected on Hosted Checkout may require a higher minimum.
Partial, failed or unresolved payments do not create available credit. If a previous top-up needs review, ask support before making another payment for it.
