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 !
As long as the operation of the cryptocurrency is completely dependent on the Internet - fiat money will not be canceled. Now there are projects that allow the crypto network to work even in conditions when it is divided into several parts. This is only the first step. Only when cryptocurrencies can function without a network at all (I don't know how), then the issue can be discussed again.
