I would suggest that ALL coins would make a version 2. Why? Cryptsy is holding a lot of small coins, KARMA, LOT, MOON, LEAF, ....
maybe they have a supply of 80% of all the outstanding coins, so we should all make KARMA2, LOT2, MOON2, LEAF2,... type of coins and swap the coins that aren't on cryptsy.
This will mean Cryptsy wouldn't be able to dump their coins on other markets and make another few millions and it can give the current owners of those coins maybe some money back if they were able to withdraw at least a few coins...
very very interesting idea
as far as understand this idea : make exchange karma > karma2 and so on : coin exchange for small coins with big cryptsy wallets
but how to exclude cryptsy wallets from this coin exchange
for most small coins only small part of cryptsy wallets known, a minority
some wallets can suspect as owned by cryptsy, but no clear proof of ownership
