Glo is a fully backed stablecoin pegged to the US dollar. Like other stablecoin companies, they earn interest from the reserves. The difference is that they are non-profit: they give all of the profit away to public goods and charity. One of the main charities they support is GiveDirectly with their basic income program.
You can help generate basic income for people in extreme poverty simply by owning Glo. More Glo adoption means more basic income for more people.
