I guess it's because of the price, maybe those who didn't have the opportunity to buy when the price was some what higher last year November and above. People especially day traders to good at taking opportunity when the see one.

4k will happen this weekend. If not, I am giving my merits to charity
I believe that those who want to make money in day trading might need to look at the benefits that could be reaped in the long term trading. The long term profits are often more big and last longer than the short term. In addition, the long term trading is instrumental in giving away experience about the cryptocurrency market and this is very helpful in future as well.
