I might add what may be very important in influencing bitcoin price movements, namely the global economic situation, which we know that stagflation, recession and inflation can affect bitcoin prices, the second thing I want to add is when conflicts occur between countries, which are often I've seen the average investor withdraw money from high-risk assets when war breaks out, just as Russia and Ukraine made bitcoin worse.
I think what I mentioned includes the big things that affect the price of bitcoin besides the crash of the cryptocurrency trading exchanges.
