I believe ETH will press $600 very soon, and I would be very surprised if ETH didnt reach $1,000 - 1,200, But I dont think ETH will take the lead as #1, but only because BTC will keep on soaring through 2018 as well.
well, I also expect that to happen. even seeing the ETH price below the $ 200 price is very uncomfortable. well, maybe that happened because I am currently holding a few ETHs, and the ERC20 altcoin. the price depends on the price of the ETH.
