The Bitcoin followers keep saying the Bitcoin is a new currency.
If that is the case then by definition it is fiat.
When it is fiat, then we will see inflation and breaking the 21million limit.
Bitcoin is different from fiat currencies, and they cannot be equal. And if bitcoin may soon become the new currency, it will act more way different than fiats. And remember that by definition of definition, it was more like a statement.
I think they are all currencies and they have the same features at all so somehow you could compare one to each other to see which one is more potiental and better than another.
