The coins viewed as valuable haven't had major issues. Litecoin in fact is going up despite bitcoin going down. Many altcoins have dropped, but only a few have been truly snowballing, tag is one of them. This is based on some charts and algo's run on the stats comparing it over the past few months.

Objective viewpoint:

* Still waiting to hear about all these business advancements
* Only public movement on the web end have been broken games
* Public mining hashrate is not indicative of being popular
* Plenty of circumstancial evidence to show the 'wall of orphan blocks' was nefarious, and not a normal part of mining (especially in light of recent admittance of various attacks, and whitepapers on attacks on altcoins)
* Very clearly an Asian coin, not a general market coin

Time will tell.
