Is it illegal to give away money to followers?

What if I said I would give 1 ETH to a randomly chosen follower this Friday? 

Screw it, let's do it. I'm gonna give someone 1 ETH on Friday. 

Only rule: Must Recast this post with what you'd do with the ETH

what to do with 1 eth of course I will invest in college, education can change a person's fate, in Asia tuition fees are relatively cheap but I can't reach it yet, maybe I want to study IT and make interesting things like you made XMTP shane which makes things easier for many people, however education is the main investment
