If you believe in the future of a stock/commodity/whatever the TIME to be buying is when the world thinks its dead or close to it.
As for analytics, there is only so far it can slide before supply and demand cross paths, thats what is happening now.
I think its a good sign that despite the low volume the coin is sliding slowly rather than a sharp crash.
Winter is almost here so its time for me to get my scrypt hardware going again, I will likely have it mining at least 50% towards buying up potcoin, the other 50% is still TBD.
Classic example of time to buy... wow it's cheap on sale, might even go lower. I think at the beginning of next year this will pop. along with a lot of die hard cryptos.
