Minds Pay is a feature which lets users exchange tokens, Ether, and Bitcoin. Depending on your and your recipient's banking details, you may also be able to wire USD and other regional or national currencies. To wire tokens or currencies to another user, hit the $ icon in the upper right corner of their channel. Follow the prompts to determine the type of funds to be sent, as well as the amount and source of your funds.
You may also subscribe to any of your recipient's memberships, or choose to setup a recurring monthly payment.
