Wow, so many posts... I think it has diverged slightly from my OP
What I meant was just to notice that it's no longer more profitable to mine PPC, TRC, etc. and the exchange rates continue to go down. All those alt-coins had a few days bubble, and it was fun to mine PPC the last few days and see 200% return compared to BTC, but that was yesterday's ride. Apart maybe from LTC that is still kicking (although at lower exchange rate that it used to), and the fact that it's the GPU miners logical path in the following months, the other altcoins are just getting slowly back to the attic.
Maybe people will just forget about them, like an old toy that's getting dust under the pile at the bottom of the toy box...
