I'm surprised this stock hasn't imploded already, I just hope that it won't take btc-tc with it.
Well, based on:
http://kryptotrader.com/api/securities.php?site=BTCT&query=LABCOINLabcoin's 30day BTC volume is about 58k BTC.
from BTCT.co's main page, they have only bone 95k BTC total trades in the last 30 days.
If labcoin drops, it will definitely take away more than half to 1/3rd of btct's total trade volume.
