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.
Lucky that the app is also a wallet then, so they can save the coins and cash them out come the end of the year...or trade them. Electroneum has been in talks to secure partnerships apparently, so I am sure there will be many ways to use the currency in the future. Being able to subsidise phone bills etc would be a huge boon to people in some countries.
