Nice post! I recently added some ZEN to my portfolio, but it wasn't as easy finding all this information as it would be the bigger coins. This is an invaluable resource!
Privacy is a big thing in crypto atm, especially as more and more government activity threatens our individual right to privacy. So I think ZEN has potential, my only fear is that with all the other privacy based coins, ZEN may be a little too late to the party.
I guess time will tell...
