Are you implying that this should happen overnight? over the course of 2-5 years? over the course of 20-50 years?
Because I bought a pair of Sennheiser headphones from a local audio equipment selling website and this in bumfuck South Africa we're talking about. I doubt the merchant is even aware they accept Bitcoin as "legal tender" since it happened through PayFast and was completely transparent to them. The point is _I_ could use it as legal tender. So from my point of view it has incredibly amount of value.
