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

Ok, this went a little crazy. Woke up to 1000+ notifications. 

I love hearing everyone’s story. The good and the bad. So many people doing good in the world and we all have our struggles. 

How should I decide or pick who to give the money to? 

I want it to be fair, and meaningful to someone.

Just peeped the OG cast had  627 recasts/quotes, I'm afraid there's not gonna be a "fair" way, unfortunately you're just going to have to pick me 😂😂😂
