is bitcoin more popular than US Dollar ?
Even a year after the post, bitcoin did not become more popular than the US dollar, because there are still many people who have not even heard of it.
Anyone expecting a world-wide replacement and the upheaval that would require wasn't exactly grounded in reality to start. The world is too large and too complex to change that quickly. I do not believe Bitcoin will ever replace fiat, for technical and political reasons, but I also never believed Bitcoin would reach $2000, either, so I continue to be surprised by the heights it has reached. World-wide currency revolution- still ruling it out.
