When people start saying "it's different this time", it's usually an indicator of a market turning.
That's true.
And it looks like Billy stumped dumping after breaking 500,00$.
Biggest dump I ever made was 10 BTC at $400 on the way up in November. I paid off some bills. Didn't dump a damn thing on the way down other than a little range trading. In fact, I'm buying. I'll keep buying on the way down until I run out of money, and then run out of credit.
With Billy I refered to this evil bot on Gox dumping ~50 BTC every 10 Minutes...
...not you ;-)
