To change your payment method for your subscription: you don't.
We currently only support cryptocurrencies for our subscriptions. You'll have to manually pay per month without recurring billing.
Will you ever support recurring billing?
We're looking into ways to implement monthly-based payments in the near future. However, at this time we only support cryptocurrencies.
