From my perspective of this extended shakeout, I believe the lowest we will go on Ethereum is around $3600 zone. I will be able to confirm on Monday, firstly because of weekend volatility and secondly because we need to see how the Red RSI is going to react in the next 3 days (whether it will close under or above 50 in the next 3D candle).
I don't know how long this shakeout will last, but there are certain levels that MUST HOLD in order for it to be considered a shakeout in an extended bull cycle. These levels include: BTC : 52K XRP : $0.85 ETH : $3600
If we keep bouncing from these zones and trade above, I will continue to consider this as an extended shakeout.
