I've been searching for any info on why this needs a coin..?
Maybe this will give you the answer:
"The purpose of Wink is to create a cryptocurrency that aims to build a new, social-network business based on selfies.
With advertisement and sponsorship, Wink will leverage the power of user-generated content over socials. By sharing photos, users will be able to earn Wink and keep them engaged with interested brands and companies.
"Wink IT" is the name of our upcoming app where people will post their photos and contests for the best picture, users will gain Wink and spend them as "points" with the companies and brands cooperating with Wink Currency."
It's on the first page of the thread.
