Hmmm, interesting but looks like it's obvious that people during holidays will spend their time with family and friends which is they gonna do some selling of their bitcoin but I never noticed it since I just started last year in crypto, I would thank you for mentioning this I would take this in my note.
The concept of holidays is over for the people who are in crypto or in technology. Their mindset is that of a workaholic which means that despite the holidays, they prefer to work and read. It is important to stay active and updated with the latest in the area you are dealing with. A long term trader would enjoy the holidays without checking the price of his coins but a day trader might do so frequently.
