Seasonal patterns been brought up before. They certainly seemed to fall in line with Christmas spending or even end of year celebrations but I always felt that people who spend on this season anyway get bonuses so doesn't make much sense that they'd liquidate Bitcoin, certainly not so close to the day itself, given the shopping needs to happen way earlier.

If anything, had I ever earned bonuses, I'd be buying more Bitcoin, instead of selling. More Bitcoiners outside Western Europe and North America too, who perhaps don't spend as much this particular season?
