Is what your trying to ask, how to get funds from a mistertango account/transaction into a transferwise account/transaction, and then be able to deposit that amount into a crypto exchange?

From personal experience, a friend tried to send funds from mistertango to my transferwise account, but he talked to support and they said they don't support those transactions (probably due to the competition). If you want an international balance, PayPal is probably the easiest way to do this, as long as you don't mind paying that much in fees. I'd recommend you to transfer the balance from mistertango to your own personal account, and then just send that via a simple transferwise transaction, or load up your account.

If you don't mind me asking, why didn't you just transfer the money directly via the exchange? Privacy, I'm guessing?
