# Transfers and Gateways
Waves.Exchange allows you to hold and transfer external currencies on its blockchain. This works through centralized Waves.Exchange gateway: Bitcoins or any supported gateway coins are sent to a user's personal Waves address via standard transfer and after the depositing user receives WAVES based tokens (wBTC) issued in the Waves blockchain. The gateway tokens are backed 1:1 with the real external coins.
Waves.Exchange allows to buy cryptocurrency using bank card.
