the ethereum is very innovative. So the price is rising fast.
A lot of Altcoins have innovative approaches, including being more friendly to fiat money banks (XRP). Still they don't climb into the $300 regions. Obviously, innovation is not everything.
A bit disappointing when you see the value of one of the best coins is declining due to trading bots!
The technology behind XEM actually encourages bot trading for a higher "importance" if I understood that correctly... Well, using Altcoins for investment is not a thing for hysterical people, I guess.
(Also: Hi, everyone. I started playing with cryptocoins rather late, namely this week, by getting myself some XEMs. Let's see how this works out.)
