HC: I wasn't watching the trades for the day. Volume was huge. Did it go off in big chunks? If so, it was probably one or two big sellers who capitulated, were tax selling, or just liquidating previously free shares for whatever they could get for them. Worst case scenario it is former insiders trying to get something before bankruptcy wipes out all the remaining equity. You shouldn't have too long to wait to find out. Cash is scare in CYGX-land. Can they raise any? If not, its over soon.
