Mudrex cannot withdraw funds from your exchange accounts as it receives no such permission from the API key. As a result, you need to add a payment method using which you pay for services on Mudrex.
Mudrex supports a variety of payment methods, and the easiest thing to do is to connect your credit card with Mudrex for fee deduction.
Our crypto payment and Paypal payment is powered by CoinPayments
If you are still unable to pay, contact us at firstname.lastname@example.org
So why wait, just add a payment method and start investing at Mudrex.
