Ethereum crossed $2900 today. I think Ethereum is also underpriced. Because at the time of the 2017 bullrun, when Bitcoin was priced at $19000, Ethereum was priced at $1300. According to that ratio, the price of Ethereum should be $4000 + now. However, Ethereum is now moving towards that goal. If Ethereum continues to grow like this, I think it will cross 4000 this month.
