ETH is facing resistance at the 0.618 Fibonacci retracement level within the range of $880 to $2150. It is currently undergoing a weak adjustment below $1660. After this round of decline, ETH will need to test at least the 0.382 Fibonacci level, which is around the mid-March pullback low of $1360. However, due to the breakdown of ETH/BTC, the current decline may potentially extend towards the vicinity of $1200. Shorting ETH may yield more profits compared to BTC.
