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

Id bribe rabby wallet dev to implement xmtp on their phone app.

Or use 1 eth bounty caster to make xmtp frame.

Or bribe infinex dev to implement chat.

Or bounty a dev to make an app which can send an email to xmtp then sign a pdf doc with wallet. (Think accepting small contract for trademen works)
