it's quite likely that Ethereum will indeed perform that well. It might be wishful thinking but there are definitely good chances of something like this happening. Bitcoin has all the attention right now and everyone will be looking to invest in it within December, once the future are available from CME group. At some point though in 2018 investors will be looking for alternatives and other coins that offer descent returns. BTC will be strong but it obviously can make the same returns it has been making for years now. The next possible candidate to be integrated in traditional investment instruments is obviously ETH. It's one of the best candidates and when that happens we'll be seeing the price going to mars and probably coming back at some point as well.
