Great article! I find myself also in the group who thinks Bitcoin will be worth more than 5k, I think even that there is a chance it will be worth 10k by the end of this year...
But... seeing that the majority thinks this makes me a bit uneasy about this... hmmm....
I also think that as Bitcoin rises the other second-Tier currencies will rise even faster... (the same holds true if it falls, they will fall faster, but as the market seems to be poised to go up, btc dominance might fall)...
Dominance will definitely fall as the ecosystem expands and more people invest.
