So when will this Xmas bubble start? Soon I hope

Isn't it already in motion? Bitcoin price is more than $460 right now, 2 months ago it couldn't pierce the ceiling of $300 isn't it a bubble?
But if you look at bitcoin price charts, year by year you will see certain similarities - around December EVERY year bitcoin price is rising in similar fashion.
And in January we have huge drop. Coincidence?
