According to Crypto Rover, if traders were optimistic about Ethereum (ETH) when it was priced between $3,000 and $4,000, they should be eager to invest at its current lower price point. This statement implies a strong buy signal, suggesting that Ethereum is undervalued and presents a lucrative investment opportunity. Traders should consider the current market conditions and historical price trends to make informed decisions. [Source: Twitter - @rovercrc]
