This is impossible. It never dropped to $6 after hitting $36. In fact, it never dropped below $30 after that point (March 2013). Did you mean $32 (June 2011)? That would be possible, but also extremely poor timing, as it was only at such a price for about 24 hours. With something as volatile as bitcoin, dollar cost averaging is your friend.
Bitcoincharts.com says the high was 31.91, for a few short hours. Either the parent comment has ridiculously bad timing and less than 20 months of patience, or is trolling us.
