If you look at why steem is a very low price it is because they want to make the blockchain that they are mining currently out of reach of all other cryptocurrency miners. Seeing how other currencies have much higher value is no detriment to steem as they want to keep other players out before they release their tokens onto the marketplace. By keeping a low profile they are able to mine their blockchain exclusively as it costs too much for other people to mine and the value just isn't there for them. Steem is a couple years out but will hopefully be worth the wait.
