The 25% BCH took away isn't so surprising - after all, it was a spectacular fork earlier this year. So we can say that, if you look at all the predictions from mostly haejin (other folks don't combine long-term prediction with TA, they just guess - while other TA artists don't like to predict further than a few days), those who dared, all landed at 20-22k or so at Christmas.
BCH has taken that away from us, we're exactly 4 k away from that goal, and that is the value of BCH... what we have now is of course a hedge, you can invest in BTC and BCH to make sure that you won't lose money when the other rises, so what the hell - the problem is that the bitcoin nimbus is damaged. People had a religious belief in hodling bitcoin, and that is gone with the wind, giving more credence to the doubters - not good, as the market depends on human beliefs... if the ver-rogers manage to get it up to about 50%, I see real danger for bitcoin classic, as people will then compare and think, "well BCH is the cheaper and faster system, otherwise bitcoin is bitcoin TM, so..."
That it's centralized doesn't count for them (BTCs lack of centralization proved to be a weakness, as all the kooks could play their games).
We should see this as a chance and even duty to strengthen altcoins, so we have alternatives next year when shit happens, as it no doubt will. So if in doubt, invest in altcoins, ideally the stronger ones, nothing below 50% allover score on coingecko (putting money into 500 no-name coins with one pump a month will just make it trickle away).
Wall Street isn't going to take the stronger alts away from us anytime soon.
