If BTC closes below the 6k mark, we have officially entered E2E trade territory. I would expect BTC to move with high volatility to the FAMA moving average (Green edge) of ~4800 price range. If we start moving towards the target price, I'm expecting the bull in BTC to use the 5K price as a nice round psychological number for support.
A great coin for leverage against bitcoin is bitcoin cash. I would recommend this option vs a leverage short position on BTC for MM reasons.
