# Token Management
Waves.Exchange provides variety of features allowing to interact with cryptocurrency. You can transfer or swap tokens, issue your own tokens, use sponsored transactions, increase the total supply of tokens 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 tokens (for example wBTC) issued in the Waves blockchain. The gateway tokens are backed 1:1 with the real external coins.
Waves.Exchange also allows to buy cryptocurrency using a bank card.
