Will the 20000 bitcoin bitstamp sell order at $300 throw your calculations off a bit?
NO.
care to elaborate?
Panic selling always pushes the price as far as it can go, you can count on it that we are at tough support here. count how many bitcoins have been sold over the down trend. A small order like 20k bitcoin is easily absorbed over the exchanges.
I respect your attempt to find order in the chaos, but you can't account for the human element in your equation. At the time of this writing, a very serious vulnerability has been discovered in bitcoin. this attack is known at the FRONT attack, i posted a thread about it earlier. Its going around on the mailing lists. The attack is of minor concern, as it would require alot of money/bitcoin to exploit and freeze the network, but its very real, and very much going to be a factor into the bitcoin price over the next few months. Entities like NSA and Terrorist groups probably have the resources to exploit this attack vector, if they so choose.
We made it through the winter without seeing a FRONT attack. Nice attempt at fear-mongering, I'll need to learn more about that one.
