Expect BTC to rise even further in price as a result of increased adoption by the Russians. Slowly but surely, the world is recognizing Bitcoin as the next "Digital Gold". I'd say Gold's "death" is certain. Possibly even Fiat, too. We'll see what happens in the long run.
Would be "dead" though? I would rather say that the two would be put on the same pedestal, being used for different cases at different times (when needed), at least by the governments (which we discuss here, not on a scale of a person and such).
