Well, I wrote at the end of October that I expected Bitcoin to close over $10,000 this 2017, so not surprised at all.
The thing is that demand for cryptocurrency is increasing day by day and there's no valid alternative to bitcoin at the moment, so all the money goes to bitcoin and the price increases week after week.
Ethereum, right now, is the only other interesting cryptocurrency. You can see this from the volume of transactions... a coin that is strong in the long run can't be surpassed, even temporarily, by coins like ADA, Einsteinium, Blocktix.
We continue to talk about projects and projects for the other coins. In my opinion, there's only one project and its name is bitcoin. All the others (except for ethereum) are called speculation.
