Is this (still) interesting? Or have we all decided digital currencies aren't worth the electrons? Here's a personalized link to contrib.com, which seems to aim to encourage tech cooperation/collaboration by rewarding contributions in their own new currency: https://bit.ly/3My0Zq2.

I won't argue with anyone who thinks bitcoin and doge are pyramid schemes, but I'm beginning to accept the idea that digital currencies might be useful in narrow barter-based communities. Several towns and cities tried local exchange token systems as a way to keep money circulating within rather than having big percentages streaming out (to national and multinational corporations), never to return.
