I agree that it doesn't look like there is any reason why bitcoin should fall right now. It looks like bitcoin price is going decent and for a bit more while it will probably go decent as well. Q1 is not guaranteed, I can tell you that for at least another month or so it may go great, but until march I am expecting some changes.

Bitcoin doesn't have a technical cap that stops the price from going up, but it has a logical and financial one where it gets harder and harder to increase, it takes more and more money to make it go higher, and we are reaching to levels where it is getting to a whole stock market prices, not just one stock, we are way beyond that, we are getting closer to whole stock market prices if we double our prices. Not USA obviously but some of the other nations, not third world nations neither, decent mid level nations as well.
