I'll buy at $1.00 to replace the Bitcoin I lost to MtGox years back
Luckily it was "just" 1 BTC.
I guess that, like me, a lot of us didn't want to store their BTC with MtGOX, it was just that back then the alternative was to use a significant portion of your hard disk to store the blockchain if you wanted to use your BTC.
Who in their right mind would store Bitcoin anywhere else than a well backed up hard drive?
I was trading the ups and downs, they didn't have any fees for a long time, so you could buy low, sell high, and repeat. Today a limit order could have bought at 31,000 and then turned around and sold at 36,000 or more.
But... never try to catch a falling knife. ;-)
