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.
For using NEM blockchain it's looking more impressive project.
