3. The statement 'little inflation drives the economy' is not the full truth. It implies that people are scared of loosing their money and put it back into the economy circulation. The bad side is that it also implies interest which feeds people who already own enough fiat money. And the real negative point with that again is that it creates a steady money flow from the poor debted people to the rich wealthy ones.
The modern concept of credit has empowered a large share of the general population and made our society much more pervious for members of their respective classes. The rise of the middle classes at the beginning of the modern ages compared to the middle ages was largely due to the possibility of acquiring wealth without owning land, enabled by lending.
Interest as part of the process of lending is not, contrary to common belief, a "freebie" for the haves from the have-nots. Also, interest is not created "out of thin air" but well-defined by the opportunity value of the credit.
Lending
can make the rich richer and the poor poorer, but it also works the other way round.
4. One very big problem is the equity covering quote for banks. In Germany it is 7%. That means if a bank has 7000Euro in its safe the bank is allowed to credit 100.000,- Euro to debitors. Inherently the money multiplies many times over a credit chain with multiple banks. This creates a big imbalance between real money and credited money with the well known risks - Lehman Brother was a typical szenario. With Bitcoin this is not possible - you cannot create virtual money - you own the Bitcoin or not - finish.
The most common misunderstanding about Bitcoin is:
"there will never be more than 21 Million bitcoins". True or false?
Well, unfortunately,
false for most use cases.
I've personally lent a bitcoin or two to someone.
For any economist in the world it is clear that i thereby created bitcoins.
Not "physical" or "digital" ones, sure, but "deposit" bitcoins.
In the future, banks might adopt Bitcoin. Let's just assume for the moment that they do, and that they treat it like any other good ol' currency. Legally, they are free to use fractional reserve on bitcoins the same way they do with the Dollar. And you damn well bet they will. After all, that's how they make money and get their little bonuses.
And people will use those "deposit" bitcoins, just the way they use their "deposit" Dollars and Euros today. And why wouldn't they? It served them well. So, for any practical reason, we should not think of the number of bitcoins as being
limited to 21 Million. It just doesn't make sense.
We would have to rephrase our statement a little to make it true:
"there will never be a monetary base M0 for the bitcoin currency larger than 21 Million".
True.
