I went to your site - I see you're using NEM for your blockchain - why them over Ethereum?
We are built for a mass audience which means millions of payments going out. NEM was built with enterprise in mind and offer a quicker, more affordable solution then Ethereum.
I'm glad you're using NEM, I've been a fan of theirs. The default seems to be ethereum even if it's not what is best for the project.
We were originally going to use Ethereum but we're built for content creators with millions of fans - all of whom can earn tokens on our site. When we hit scale, we didn't see how it would work. NEM was built for enterprise in mind so it just made sense for us.
