There are plenty of examples of how price deflationary economies grow and thrive. In fact, it is inflation that stops growth because it creates malinvestments.
The problem is that keynesians ignore the empricial evidences and keep repeating the same nonsense. If Bitcoin works or it does not it wont be due to price deflation.
1 internet is worth 1000 internets. Bitcoin is a set of protocols as is the net. A crash would be an opportunity of a lifetime. All that would occur is a reboot with hindsight. It would be criminal to not take a ride on a much stronger project at flea market prices.
Honestly, I have started mining now so it goes against my short term interests, but deep inside I hope Bitcoin collapses and a lot of the people that is in here not for the community or the currency and just purely for the monetary gain go away. Nothing wrong in wanting to earn money (I do), but Bitcoin is much more than that. If Bitcoin crashes to some degree and some people get caught on it, maybe we can focus 100% in Bitcoin as a currency and have a nice community here.
