# Asset Management
Waves.Exchange provides variety of features allowing to interact with cryptocurrency. You can transfer or swap assets, issue your own assets, use sponsored transactions, increase the total supply of assets that you issued or burn them to decrease it and more.
You can hold or transfer WAVES and other cryptocurrencies on Waves.Exchange blockchain. Bitcoins or other supported external cryptocurrencies are transferred by means of centralized Waves.Exchange gateway. This means that the coins are sent to a user's personal Waves address via standard transfer and after the depositing user receives WAVES-based assets (for example wBTC) issued in the Waves blockchain. The gateway assets are backed 1:1 with the real external coins.
Waves.Exchange also allows to buy cryptocurrency using a bank card.
