This is a really nice Idea to Distribute the coins via Facebook and other social media Platforms.
I signed up today and already referred some people through Twitter!
It is a really good and early way to get some free valorbit.
Because if you sign up you get 500k free already and 1 million if you invite someone!
 

Yes I think so as well they will get a lot of exposure themselves, because they are the only legit place selling Lisk.
But because there is a limited Supply the price will go up quick, But it good the Devs released a Statement so quickly!
