There's an inflation of currencies on top of the inflation within each currency. The cryptocurrency system will tend to stabilize as it matures, new currencies will have difficulty getting a ranking. And even with a milion diffent currencies some will have value, these are the ones at the top. It's getting more important to be at the top now because it's later in the game after last bloom of currencies. Compare it with companies, thousands of new companies created frequently still don't have any effect on the stock exchange rates for the well established ones.
It's worth noting then that Fastcoin has kept its market cap ranking in relation to the number of currencies out there, a stabilization sign in the face of so many new. Fastcoin is in the top half, precisely, some new got passed, most behind. Also interesting to note that the inflation caused loss of value has happened with altcoins in relation to bitcoin, whereas bitcoin is stronger in comparison to altcoins and doing quite well in dollars. This is just a temporary set back for top altcoins in my judgement and a strong bitcoin is paving the way for altcoins, so it's a win win depending on time perspective.
When I found Fastcoin and bought in at around almost three times todays value I was excited to find an idea, fastness, with great potential that was still not found or valued by many, or had been rejected due to appearance. The reception of Fastcoin on bitcoin talk (go read it if you haven't) was pretty much 3 pages of people claiming they did not know if it was serious with all the cheetahs. All such appearances can change though, and has started too, and then Fastcoin is taking off. If like a cheetah, then like a serious one, imo.
To make it clear I'm holding and increasing my FSTs right now. You may equate any comments on such as trollbox stuff but I have provided my argumentation (free to use or dismiss) and wouldn't mind hearing some elses.
