Especially the fake news part seems huge, i mean they all said clinton would win lol
They reported about polling which suggested Clinton would win, and made a prediction - that's a far cry from "fake news", which would be implying that there's a 100% chance that Clinton would win regardless of circumstances and treating the news piece as fact rather than as opinion.
Similarly, suggesting that Bitcoin is a bubble is certainly subjective and could be true, so I wouldn't call it fake news at all.
It cannot really be just a coincidence?
Well I'd say that it's at least partially coincidence - after all, those factors you mentioned
would probably affect the price of Bitcoin, but not to the extent that it's risen over the past year or so. It could of course be entirely coincidence, just like the many completely unrelated things that happened at the same time as Bitcoin's price rise, but I suppose it most likely had at least some effect.
Still, Bitcoin probably has a very high amount of amateur investors relative to the stock market, and a lot of investors that attempt to bypass regulations, so they're probably less affected by changes in taxes than stock market investors.
