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!
NO absolutely, Traditional trades using money, or other kinds of money will not be replaced in the future ! Because NO one is willing to put their career of their properties on an ONLINE SYSTEM which is easy to be hacked !
