Why would I want a physical currency whose value that is subject to the whims of a higher power, when I can have sound money that doesn't lose value everyday?
Where can I find this sound money that doesn't lose value?
Funny, but it isn't fair to generalize the context of his statement. He said "that doesn't lose value everyday;" this is an expression, and not to be taken literally. If I interpret him correctly, he is asserting the strength of Bitcoin in its evasion (or rather, structural immunity) to the powers of centralized authority.
So basically his statement is incorrect, misleading, and completely worthless. EVERYTHING is subject to value fluctuations in an open market. I'd take a currency that doesn't lose value over one that does anyday... but that's irrelevant because that currency doesn't exist and never will.
