Ponzi scheme on steroids
Have you had a chance to check out the website and read the white paper? If not, Id recommend doing those two things before jumping to the ponzi scheme conclusion mate. 
I usually put up the FAQ (https://www.merit.me/faq/#how-is-merit-not-a-ponzi-scheme--how-does-it-relate-to-mlm-businesses) to explain this. Hope this helps.
