Question: What is your top 5 Cryptocurrencies (non payment-gateway/ blockchain based app) on https://www.coingecko.com/en ?
What do you mean by "non payment-gateway"?
Not Ripple is the way I read it......probably not Stellar, either.
My Top 5 picks are easy: NXT, NXT, NXT, NXT, BTC.
(though I do like BTM, BTCD, Noble and maybe UNO for the long term)
