It’s not much but I believe if everyone is doing their part we succeed in the long run

I agree completely with this. I only donate a token amount of ~2 EUR per year to some projects: it won't do anything by itself, yet still, if everyone did the same, it would be really impactful.

For a few projects that are most important to me, I donate up to ~15 EUR per month. It's both a lot of money, and also not a lot at the same time. By itself, it still has a tiny impact, but it is a decent monthly expense, especially when donating to a few projects.

To me it really highlights that we can't help fund anything by ourselves. After donating some amount yourself, the next best thing you can do is encourage other people to donate too!

There's a really cool project called Snowdrift that tries to harness that dynamic. They came up with a concept called "crowdmatching", where everyone's donation is linked to the number of people donating to the project (up to a cap).

Although progress on that project is quite slow, I really hope to see it succeed some day, as I think it really thoughtfully and neatly manages to coordinate people to band together to fund projects, and make a real difference as a group.
