First let me explain, what I was replaying to.
The OC argument to seems to be, bitcoin and beany babes are expression of the same idea and beanie babes flopped. Ergo bitcoin will fail.
Hence the question about greenbacks, which are now not worth a continental.
Yes, you can say that greenbacks are doing great, comparatively speaking, but than if greenbacks ~= dollars and beanie babies ~= bitcoins, than you are bound to say that.. beanie babies are at least moderately successful
Which if I understood the OC correctly it is exactly the opposite of what was implying.
