it means this is the good time to buy coins and hold those into some days because the price will increase soon the big market is coming.
Yes this is the best time to buy bitcoin because I think the base line for bitcoin market price has been establish already. 3K + USD was the cheapest market price for crypto being recorded for 2018. So, I guess the base line was being met and this is the right time to buy bitcoin, hold and sell in the near future.
