Once some altcoins start to pump little by little Bitcoin fell from 3800 to 3500 and standing still right now. I think someone is just trying to drop out Bitcoin's price.
I do not think that the price of bitcoin can be reduced further. If we come down to less than $ 3500, we will be in a much bigger crisis, and we will see a collapse that will be very difficult for all altcoins and bitcoins to come back. Perhaps to wait for years to come back to the old prices
