I think it is very possible. $240 is not that far from the price of Ethereum right now. Ethereum is just barely hanging on to $300 as of this posting. If Bitcoin will go on very bullish, there is a probability that the alts, even ETH, will be negatively affected. But there is not need to worry much. It is just a matter of time before the altcoins will also start their own bullish season. And by that time, ETH will be the leading coin. Store as many ETH as possible today.
