As I said, I agree when you get to the point where it actually resembles a global ledger. Something that grabbed 0.2% could still be overtaken by something that grabbed for example 1%. But if and when you get to 20% or 80% or whatever, then no.
Right, all in context.
A good example is that in Japan today I learned Bitcoin is getting so little adoption (due to MtGox being all they know of it) that Ripple is actually ahead in terms of total amount invested (they used MLM/Amway to sell it
). When you have an entirely different population to choose from, nothing I said about precedents regarding SoV applies, since the new population is unaware of the precedent. For practical purposes, though, I don't see something that is very much like Bitcoin being able to pull that kind of "new population group" trick, unless circumstances change in some unforeseen way, possibly regulatory.
