In the last months I found myself using nostr:npub16l6vecvkh6fz4uegf3r84cj72zh7l606rt9x39zqvv8vxhku9luqss4zxy more often than originally expected. I decided to contribute to the project with small monthly donations. In my opinion this is the best way to nurture a long term support. Consider also supporting the development of your favorite free software apps with small recurring donations, not only will you support the developers but also help to make a better world.
