It's really interesting to see this. This is my first January in crypto and I'd heard it was traditionally a bad month for bitcoin and crypto as a whole, mostly I just figured it was some strange coincidence but each year it happens it's becoming less of a coincidence. The question then is why is it that January is such a bad month? As of yet I've been unable to answer this one.
I think it's just a guess that the Chinese are celebrating New Year.
There are certainly more reasons but this is one of them.
