1) leaving some btc in instawallet. no word yet from them on how serious their security breach was and if our coins are safe. that might end up being a mistake for me, hopefully not though.
2) thinking i knew how to day trade. luckily i only lost a very small amount but the constant small loses made me realize i dont know enough to be playing that game
3) thinking bitcoin was really awesome 3 years ago but never jumping on board until recently. that one really hurts.

Purchasing a BFL with bitcoin early. If I make back 30% of what I paid for it I'll be happy.
Lost 7,4 BTC to a thief. I was stupid enough to keep a hot wallet in a windows machine.
How exactly was the machine hacked?
I am still unable to figure it out. I have installed an antivirus (avast) but it found no trojans yet. The BTC was stolen yesterday, I think the wallet might have been purloined sometime last month.

Cashed out all my casascius coins (50 BTC worth) at $27 to pay some debts.
some debts..
sent 45BTC to an anonymous mixer on TOR.. they never returned
Ouch. Was it a well known one?
Accidentally received coins from a friend to a bit-bill in my (physical, leather, back-pocket) wallet whose private key I had previously posted on my blog as an example. The coins got swept after only 1 or 2 confirmations. Fortunately it was only lunch money (although someday it might be worth a few solar systems).

Nothing.
I regret no decision although if I had the chance to go back knowing what I know now about the future I would have done a few things differently obviously, but given the information I had at the time I think I made good choices all around, choices that were based on empirical evidence and sound conservative reasoning.

Formatted a hard drive with unbacked-up 10BTC wallet........ confident that I would find a backup of it someday....... someday..... 
Lost about 200BTC on GLBSE
I learnt a valuable lesson, it's rare that any investment can beat price fluctuation of Btc itself, the few that do, you lucky if you ever notice it.
Amen brother 
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:

My greatest mistakes:
1) Did not buy any when it still was cheap arount 5$
2) Did not buy any when it was rallying over 10$
3) Did not buy any when it was rallying over old ATH 32$
and so on...
So I will prepare for the next dip - I will fund my Mt Gox account and buy lots of coins if and when we get 20-30$
Since getting involved in bitcoin I made 2 pretty big mistakes;
Selling a large portion of my bitcoin stash, when it was worth £9.
It's true I needed the money, unforeseeable situation meant the bitcoins I held, was a big life line to me.
Then to watch it jump upto £75+ over the next few months.
It just hurts to realise if I could of held out, I'd be have 8x that figure, which I admit I might of been able to do.
My other big mistake was "gambling/investing" with my bitcoins via assets on GLBSE.
The only upside is ASICMiner (investment) turned out so profitable it made up all my loses in all the assets which didn't.
