40-60$ is not possible this year or the next, I think by 2020 it could be worth that but only in certain circumstances. Remember MNEv2 is coming out soon, and eventhough you need the first coin to buy them, we don't know how many coins will be sold, and therefore how many MNE will be bought and burned. Overall with a limited supply and automatic deflation of the coin, I think MNE could prove to become very valuable, and I'm definitely accumulating, but my best guess is that 25$/coin is a very realistic bet for 2018.
