As the topic says,
What are the biggest mistakes you've done with Bitcoin?I'm trying to gather just a list on things that have gone wrong. This can be terrible backup stories, client hacks, reversing at MtGox and such.
I don't want to gather a list of hacks of commercial sites in particular because there are plenty of information on that already.
I will post everything I find on this very simple website:

EDIT: Please add some context, interesting details etc to make it a nice story.The biggest mistakes I've ever made was, when I sell all my bitcoin at 800$, which I shouldn't do it, it was so very regrettable because look at the price now almost 1251$ and worst in my part its getting more higher in the coming weeks. So now I'm starting again to buy bitcoin little by little and I won't sell it until it didn't reach 5000$.
