Although there are no concrete evidence, I think mainstream events somehow affected the bitcoin price in market like what happen when the US government conduct an auction on the year 2016.
As we all know bitcoin results to a bull run in 2017 that is why many people today are talking about the auction this year by the US again ranging from 4,000+ BTC that is acquired from criminal and  illegal cases.
Maybe these big event can cause a drastic increase to Bitcoin Price again. What do you think?
