Alts Season! But this time It's Winter...

Some call it scallop, saucepan or other names, but I call it Altcoins Slaughterhouse!
It seems Bitcoin dominance is going to have a big growth up to 78.9% and it will not be good for altcoins at all. But what about BTC itself? Is BTC.D's growth because of BTC pump or of Altcoins' decline? I say a little of former and mostly the latter.
Then, what is price forecast of BTC in this regard?
Stay tuned... ;)
