I think, that this coin could have a huge support in "third world" countries, because people will be able to mine it practically for free, and every earned cent is welcome.
Unless they are able to use the currency to pay directly for goods and services at point of sales, no intuition will convert the coin into fiat in such minimal denominations.
They will be able to transfer ETN between each others accounts through the app, who says they will not trade with it that way? e.g I sell you 3 oranges you send me 25 ETN through your phone to my phone. People in third world trade all sorts of things for services and food not just hard cash.
they might open small fiat trade offices - where u can buy etn for cash to send to the grandma - or get cash for received etns......
btw i dont understand people talking the mining app is a fake? not realy adding cpu power? thanks for help
