Something to bear in mind, that TransferWise’s stance on cryptocurrency transfers either directly or indirectly, are not supported.
So if you’re looking to use TransferWise to transfer money you got from Bitcoin, be prepared to have your transaction rejected, and possibly your account frozen and closed.
Also, we cannot support transfers from or to Bitcoin or any other cryptocurrency, directly or indirectly, through our services.
