Too late, they pump about every six weeks (last time was Mid November, same effect) - thats all it is, a pump by Chinese Miners (mostly on bithumb), and those who get in too late, lose their money. There's still a good chance to buy bitcoin cheap at this time, though. BCH - I would wait for the next likely pump around end of January, likely together with some news about "Wall Street getting into crypto investments soon"
BCH isn't worth it, I would prefer Litecoin to it anytime, there's just the cognitive dissonance as the name begins with "bit" - just another altcoin really.
However if enough people suffer from cognitive dissonance, it will become their god.
