This is going to be a really short post, because I don't want to bore the hell out of you.
Money and currency are terms that are used interchangeably in modern society. But in reality, their differences cannot be greater.
So, which one's which?
As the above diagram shows, money and currency have the exact same functions. Divisibility, fungibility, durability, portability, interchangeability. Whatever.
The major difference is in the long term store of value.
This is why fiat currency isn't money, guys. Fiat currency is currency. It doesn't retain purchasing power in the long term.
In my opinion, gold is the money of the past. Silver too. In a few decades time, the next generation money will be cryptocurrencies, such as Steem.
If you hold any form of fiat currency - I suggest converting it into Steem right now. Even if Steem crashes - which I don't think it will, at all, it will outperform fiat currency in the long term.
