I was there when MtGox got hacked, and when bitcoins where selling from $30 to $32, but that was over a year ago.
Well over a year ago...
Here's 18 months, today's exchange rate hasn't been seen in that long.
There was only one big (real) market crash, in May-June 2011, mainly fueled by the MtGox hack and magical disappearance (and selloff of stolen funds?) of mybitcoin.
