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

Wow, 1 ETH will go a long way for myself and humanity's sake. It will be used to help many potential talents in the basketball world, particularly in Nigeria, where there is a huge passion for the sport. There are many young Nigerians who need support to develop their skills and pursue their dreams. The funds will also support those without a roof over their heads in Nigeria, providing shelter and hope for a better future. Additionally, it will help combat childhood illnesses that are prevalent in the country. I'd be glad if these dreams could come true through your support.
