I understand that some of you don't agree, but that is no reason to effectively DOS attack this thread with an off-topic discussion.
Oh come on now, it's a fun discussion. And it's really hard to come to terms with an idea as specific as "minimum income" fitting into a decentralized cryptocurrency system. However...
This thread takes it as a given that a basic or minimum income would be desirable and effective, and asks if it can be done via an altcoin system, and if so, how best to do that.
If you can broaden your definition of minimum income, you might be interested in discussing the Decrits proposal:
