I am sure many events recently influenced bitcoin: news about tether, incoming futures date, regulations of several countries, but do you think that Chinese New Year could also influence it at some point? Perhaps many Chinese are withdrawing now in order to purchase gifts for their family member and that could influence bitcoin rate.
Every year christmas and chinese new year doing some changes in the marketcap. This happening since the 2013 so you do not need to worry that more dips in the market. Everything will recover a week of time. If you watch the price changes in the complete one year. You can find where I am standing on this point.
BTC rate make the more panic to all their investors but everyone here do not understand the crypto currency and leaving out from investment. If you are in you will one the millionaire in crypto platform.
