Expand that chart out to a year or better and you can make the same argument for Bitcoin. My point is simply basing what a coins long-term prospects are by looking at a few days worth of graphs and proclaiming its demise (or success) is pointless. FTC may very well disappear, or it may decline in value some more only to slowly regain its value over time and ultimately become worth way more than when it first hit BTC-e.
One point I will agree with is that all the alts, at least for right now, live and die by BTC. If BTC heads back to $270, even the 0.002 FTC/BTC will be pretty profitable.
I tend to play both the short-term and long term positions with all the coins. If I can get in a mine a bunch at launch, I will sell maybe half up-front to take some profit, and just sit on the other half for the longer term. I am not too worried what happens over the next days/weeks as I am months/years.
