Is any body else getting weird readings from Bter.com's chart?
I'm guessing they've recently upgraded it, and with YAC, if your time frame is 'all', It shows it from 1970 (after a while).

YAC was worth 1,368,509,400,000BTC in 1970

(I don't even know how to say that number)
Is this showing up for other users?
