What role does the coin have?
In my opinoin, this kind of coin might replace "real" money in the future.
I don't think so. It is unfeasible that coin replace real money! just some kind of money on internet!
you never know what will happen in the future, like nobody would even think of having internet back then but now it plays an irreplaceable role in our lives today. i think the same goes for these coins, it's still in its infancy anyways.
