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

If I win 1 ETH, I will use to build out a fun frame for us to play with on the timeline in the next few weeks

You should recast my recast so I can give you some ETH to build the frame
