I think those new altcoins popping up from anywhere are no problem for the community or a threat to other coins.
Why?
- strong coins with support by community and/or developers behind it, like LTC, WDC, PXC (!) and FTC, will survive anyway
- by moving away hashingpower from these coins to P&D coins, difficulty drops and more coins for you and me
- coins that are "pump & dump" will die eventually, only coins that can be actually spend somewhere or adds new features has any chance of surviving
- Cryptsy can't just add altcoins forever, nobody visits an exchange where you have to scroll down 26 pages to find a coin
Just support your own favorite coin(s), the strongest one(s) will survive eventually!
The true strenght of an altcoin is you!
Stand by your coin!
Ask not what your coin can do for you, ask what you can do for your coin!
Let the coin be with you!
Cryptsy hides coins you don't have a balance in now so not an issue.
