Don't see anything here that I identifies with the current situation. I don't think a lot of those that expect a crash greater than 61.8% understand the sheer amount of money that was and is still coming in. Over 225 Million dollars has changed hands in the last three days alone, just on Mt. Gox along with 2.25 Billion Yuan (~367,000,000 USD) on BTC China.
OP, before shorting, you should do some extrapolations and atleast integrate some mathematics instead of trying to confer something with which you cannot grasp.

But here's a pat on the back for trying OP.
That chart has been used to validate week hands and over leveraged investor's liquidating BTC holdings at $4 $12 $31 $266 $?
Those that use btc as a headge against inflation have historically succeeded by using the buy and hold stratigy.
If you must, set your entry and exit point and don't let market day to day sentiment sway you.
Yet realize that exiting BTC to your fiat of choice will leave you with a bad after taste.
Unless of coarse that move resulted with you having more BTC and debt free in the end.
