The last few weeks of the year for BTC usually don’t see much interesting price movement.

Except for 2013, 2017, and 2020, things have generally been pretty flat.
Interestingly, the extra day in a leap year usually brings decent returns—something I hadn’t noticed before.
Overall, I don’t expect any major volatility until the new year begins.
Typically, the market is quite choppy at the end and beginning of the year.
Especially during Christmas, both liquidity and trading volumes are very low.
