We have far too many inflationary currencies. So it feels right to have something different for people who believe that reasonable deflation is in fact a good thing.
And it is not to say that it is a good or bad thing--I just believe in the free market and
actual freedom. I think the choice of a deflationary currency--like gold has been for 1000s of years--is an intelligent investing choice. That is why I'm interesting in bitcoin.
Yes, deflation does cause for hording and causes for the velocity of money to plummet in times of crisis when there is only one currency--but we live in the real world, so a deflationary currency is great for saving. It's really shitty for doing loans--which is what 95% of the 'real economy' is based off of, so that is the greatest disadvantage in my mind. I'm am sure however someone brilliant is already working on an algorithm that could give bitcoin loans in a way that wouldn't totally fuck you on the payback later down the road.
