You can see on this lifetime chart the pennant formation that has occurred. Using ATH of approximately 20k and low around 2k. You can see here that BTC is in danger of breaking out below lifetime pennant which would be approximately 4800. That is a very key lifetime support level. If breaks below this for any extended period and 4000, 3500 and 3000 are back in the mix. Keep an eye out and trade safely!
