if we think that the events of today are almost the same as the events of a year ago, maybe this is the Christmas trend and the new year that makes people must hold cash to celebrate.
i dont think its the same as the last years december because some people said that bitcoin has increased on the last december 2016 but bitcoin on this december 2017 has decrease dramatically due to the cause of correction however holidays season has also the other factor and reason on why bitcoin has going for a dip thesedays. yet it is still a win win situation for most of us because now is the perfect time to buy and horde more bitcoins.
