are the price movements related to those speeches of the central banks such as the BOE?
Due to that news and FUDs that are coming from banks in different countries stating that they will ban or regulate the use of bitcoin, it creates panic on people so in result, most of them are selling their fair share of bitcoin while they can see some profits before its too late for them to sell out and wait months before the price recovery. So banks affect the price of bitcoin one or the other.
