I don't offend you, but I think it's best to let December is December.

Don't try to input or extropolate the month word December to anything else, because December was not born for any meaning you want to attach. December itself is not an abbreviation, so if you try to attach some other words to each of December characters, it's too reluctant.

What does December mean for investors and traders?
See its history.

In Bitcoin monthly returns, there are two statistics for December:

• Average: +8.65%
• Median: +3.27%

It's not a too good month for short term profit.
