This is a cool idea - but I wonder how well Bitcoin (specifically) fits in with the values of the community, what with it's
intensive energy consumption. I don't mean to bring down the party, but there are plenty of other more sustainable coins to play with. There's even a "regenerative currency" coin called
Seeds which might fit better. Although it's not as valuable as BTC it may be a viable option. The team at SEEDS is also open to working with organizations, and there could be some collaboration opportunities here as well!
I've got a contact of one of the peeps behind it, so let me know if you want to connect with them.
