Granted, the evolution of Bitcoins is quite unique compared to other currencies, but I still say misers theorem holds here.
No, it's not. You guys switched from the crucial point - an existing pre-monetary value of the thing that becomes money, to the secondary one - the process (barter) by which this thing emerges as a universally accepted medium of exchange. It is like declaring that water is good for fire extinguishing because people tried different liquids for the task, and water proofed itself the best one. It doesn't follow, however, that water properties have nothing to do with the matter.
This is the weakest spot of Bitcoin. In "Human Action" Mises said that valuation of money (true money) always includes two components - valuations of its monetary and non-monetary properties (F = M + N). What does this mean for gold, for example? It means that if, suppose, some nerd, having been hoarding a huge pile of gold, suddenly releases it on the market, he, theoretically, can destroy the M component. Suppose even people would think that gold is not a good means of exchange anymore. But he never can destroy the N component, because it resides in the properties of gold that have nothing to do with the exchange process. Gold is needed as a consumable material for jewelry, medicine, electronics etc. So immediately after the intervention stops, the N component, so to say, kick-starts the process of imputing the monetary value to gold. The question is: where is non-monetary component of Bitcoin? There is none. That's why Bitcoin is vulnerable to all kinds of "loss-of-confidence" attacks. I think that this is precisely what Nenolod is doing right now.
According to Nenelod he is NOT doing that. he has as many coins as he needs and is on to the next step in his project.
Is there some minimum value that N has to have? Are you sure that N is exactly zero for Bitcoin?
I'm eagerly awaiting "loss of confidence attacks".
However, it does not follow, that the characteristics of water have nothing to do with this problem.
I think it is objective.
