We need altcoins as long as we interact economically over the net, with people we do not know (or simply with people outside our local communities). If we try to imagine what qualities a “solarpunk coin” should have, what are your thoughts? Do we know any existing coin, checking all boxes? This question is more about political economy of Solarpunk, then its technology.
Yeah I’m not really sure how to overcome this. Maybe povoq is correct that money printing is an easier solution, since it doesn’t require direct participation from the wealthy.
I’m still interested in experimenting with this idea though. Most other forms of wealth besides money have downsides, even gold. Hoarding physical goods is harder to do secretly and requires storage and security costs.
