Theorem:
The soundest form of cryptocurrency shouldn't have to fight for "popularity" amongst others, nor will it. In the long run, sound money is not a popularity contest.
A cryptocurrency's economic/governance model and strength & security of its network should speak for itself, and become self-evident to all involved eventually over time.
Other, lesser cryptocurrencies will eventually wither and die.
Question: Does Gresham's law apply to the world of cryptocurrencies as well? Hmmm...
Also, go Bitcoin!
