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

Firstly I want to thank you for an opportunity like this

What do I need 1 ETH for: a lot honestly but will say a few

-Complete my rent
-Send some home(family)
-Use some to round up from school 
-Lastly will pay for courses/skill and grow from there
