- The coin supply *will* be inflated beyond what was originally promised. History has shown that *all* humans with the ability to inflate the money supply eventually take advantage of this power. If there is a "backing," it will eventually become meaningless, as history has also shown.
This is the main point I'm in disagreement with most people over.
Because the argument isn't that a centralized coin will be awesome and amazing and will replace Bitcoin because of that. It's that a centralized coin, even though it's worse than Bitcoin in many ways, will gain widespread adoption quicker than Bitcoin, and over-take it very fast. Or at least that it has the potential to do so, depending on how its issuer plays its cards.
You're absolutely right that it will be inflated, destroyed, and taking advantage of. But that will take a very long time. The Fed was founded 100 years ago in 1913, and the Bretton Woods system has been around since 1944. Almost as soon as those systems were established, you had people opposing them on very similar grounds. That the government shouldn't have that kind of control, that it will be inflated, that it's economically irresponsible, that people will suffer in the long run, etc.
And guess what? Those people were right. And yet the USD is widely adopted. It has many "users" throughout the world. And the people who control it have great power.
So I have no doubt that if Bitcoin demonstrates demand for a crypto-currency out there, and TPTB create their own crypto-coin, that they can get widespread adoption over Bitcoin in no time.
