Right now, as it's an experiment, I'm personally paying for the ads myself to promote the wallet and reward early testers. We're also in talk with other bitcoiners/potential advertisers and we plan to eventually have more external businesses funding it obviously.

We will also support credit card subscription for channel opening and receiving ads rewards. With this model, we won't have to rely on external businesses to fund the ads and practically help people get sats without KYC.

The business model for Diamond Wallet is still in works but I believe I can come up with something sustainable.
