How much Bitcoin is going to fall down?

According to the Fibo levels and the support line that I have draw on this chart already as you can see, the next support level would be around 43000 area for BTC.
therefor I will look for a weekly candlestick pattern as a reversal signal to buy Bitcoin in that zone. you can also see the same pattern in weekly timeframe in my analytics that has caused the fall.
Stay safe.
