The game will start getting quite interesting when individual coins start moving around on their own. How long that will take, I don't know... right now we're just at the stage where everything-- as perceived by the broader public-- is either "Bitcoin" or "like Bitcoin." Most alt coins seem to have zero identity of their own outside the limited realm of cryptocurrency enthusiasts.
Steem is sort of interesting because of the whole social platform and the increasing number of initiatives to create an underlying economic base here: @steembay, @ steemgigs and so on. With the basis for an actual ecosystem economy being slowly laid, I have to wonder if Steem will be one of the first alt coins to "break loose," so to speak.
I used to hold some conventional assets for investments, nut it has been many moons; we liquidated pretty much everything to buy a house and land outright with cash.
I will be doing similar in a few years to build a eco-sustainable house... somewhere... hehe.
