Launching an erc20 on eth is super dumb. You will destroy most of the value just sending it to folks, and they will need to then buy expensive eth to spend it. Makes no sense.
Global Income Coin is an economic model carrying a monetary policy: the bottom-up distribution of newly created money. The economy currently mostly runs on inflationary currencies. This means a massive amount of new money is created each year. Taking that as a fact, we propose to distribute this directly and more fairly; Global Income Coin is the implementation of that idea. Sats can't carry that monetary policy since they're non-inflationary by design. So we can't use sats.
> Lightning network is the only cryptocurrency construction that would permit such global payments
We _could_ use Lightning, and we might indeed in the future if that's the tried and tested best solution. We're not married to any particular platform. We don't need global scale on day one.
We're starting on Polygon (so transaction costs won't destroy all of the value)
