Glo Dollar

Glo is a fully backed stablecoin pegged to the US dollar. We're non-profit. Like other stablecoin companies, we earn interest from our reserves. The difference: we give all of it away to reduce extreme poverty. You can generate basic income for people in extreme poverty simply by owning Glo. More Glo adoption means more basic income for more people.
