Let's stop the rumor mill. Why would Poloniex delist the excellent Clam coin?   Sounds ridiculous.  It's a great coin, solid features, support and community, generates significant volume for them, and they are the primary trading site, making a tidy profit.

It appears there may be confusion in regards their notice at

where they will stop **margin** trading, for a while, on Clams, Factom, BTS, MAID, out of market depth considerations.

That has nothing to do with Clams trading in general and overall listing status.

It fact, it's a great move, they should never have allowed in the first place.  The margin pool on Clams was a terrible vulnerability, and is exactly a fault cause of the recent price drop, and possibly the prior one too.  It's very good for Clams that Poloniex remove exposure to the margin pool.
