OS University Airdrop
Very great project! Nothing to complain about the project itself. Just about the airdrop itself, because you only receive 10 EDU for every person you refer. That's a huge downside (minus 2 stars). But on the other hand 1 ETH = 750 EDU. So the 10 EDU are worth around $9. This is plus 1 star for such easy steps to participate!
