The closer to Tet, the narrower the market range.
The period in the final days of the year is also the time when funds have closed their books to prepare for the Christmas and New Year holidays. Therefore, at the end of the year, no fund wants to take risks in the last few sessions for any reason.
Almost all price plans of the funds have already been priced into the market during the period of November and early December. Therefore, you will see the market making a very strong move in early December, and immediately after that, the market does not have many strong fluctuations as it has completed its price targets for the year $BTC
