The Bitcoin price is still a dip. Even when it reached 11.2k today, it was still investible. The recent negative correlations is because all the events going on with crypto right now through either a regulatory, business, or criticism standpoint. This includes many people worried about an institutional takeover of crypto, as well as the "civil war" going on with Bitcoin Cash and its probable instability, among others. However, BTC still ranks supreme over a fork or takeover. Another reason for price dips is the increase in pump and dump ICOs. This is a reason to be careful with investments. However, Bitcoin among many high profile useful altcoins are a buy & HODL strategy as far as I am concerned. There is even a possibility BTC can hit 65K+ by the end of 2018.
