Look at the long-term graph for any old coin that is on Cryptsy, they were all dying, getter lower and lower from September to November. Then you know what happened. Just sayin' 
Yes they then exploded due to articles in the NYTimes and Wall Street Journal etc brought new money in, now it seems the only money goes to the latest pump n dump scam...........
cryptsy plan to add new take out old will just create a cycle where only money can be made by those in and out of the new coins as quick as they can then move to the next......that game will only ever last a few rounds, too many people get burnt and leave.
thats a win lose model...that leads to a lose lose model
yet it is possible to have a win win model.
sometimes they write back saying "I didn't ask for you to deposit $1k, or join any program, when their specific (or most) say "get in now, deposit and join....."
