Bitcoin had experienced a huge fluctuation in the current crypto market and in my assumption, this fluctuations are merely just temporary for it will recover soon. The best approach for most of the people holding their btc's is to hodl while market is down and buy more btc during dips since there will be time for it to make a recovery soon. This strategy seems to be very effective as veterans of the crypto market were doing such moves and later gain good and generous profit later when market had fully recovered.
This strategy has worked before. But now the market situation has changed. People with big money came to the cryptocurrency market. They thought for a long time that bitcoin is a fraud but now they have changed their attitude to it. Big money will allow them to increase the duration of the downturn periods. Only those who will have the opportunity to wait for a long time can win.
