Ethereum [ETH] followed Bitcoin [BTC] in registering significant gains over the past week. ETH’s bullish rally from the $1,550 support level extended its gains to 20% with price trading above the critical $1,800 price level. This surpassed the $1,700 target AMBCrypto had predicted on 23 October, based on ETH whales’ accumulation. With the $1,800 price level flipped to support, bulls could be looking to hit another price milestone at $1,900. After bulls rallied from the $1,550 support and flipped the $1,619 resistance, key price hurdles were identified for the bullish rally at $1,680 and $1,745 respectively.
