What are the biggest mistakes you've done with Bitcoin?

[mb300sd]

lost a 5k+ btc wallet to a hard drive way back when
bitcoinica
pirate
bad trades
satoshidice
cashing out 5% at 32
...
the list goes on, but I'm still in an ok place, and far better off than I would be if I never got in.

Spending BTC100,000 on a few pizza's. It's not the $14M I would now have that bothers me. It's just that I can't lose the extra fat and love handles I now have.

1) Not mining harder two years ago, I bought 1x5770 when I had space fro 3x ( I didn't realise I sould use PCIe 1x with a riser)
2) Not discovering Bitcoin 6 months earlier
3) Not mining in winter of 2012

Could have been rich.... now I've only got pocket money

Paying for mining equipment in bitcoin instead of USD. But that is circumstantial. Had BTC gone down in price, I would have been better off. I admit I had less confidence in the system back then.
I am also not a large risk taker to I wanted to keep my risk within the bitcoin ecosystem.

Even earlier on, forgot the password to my first wallet containing 3BTC. Then found out that I had also lost the wallet.dat file when I tried to look for it this year.

Gambled 1btc away. Yet my biggest mistake. I don't consider missed opportunities mistakes though.

Not getting into the mining business in 2011. My motherboard is an old one, without PCI-E sockets, and I didn't want to renew the whole computer since it worked (and works) fine.

1.) Installed the client some time around December 2010. Set it to "mine". It made my laptop go loud and hot. Nothing else happened for the 30 seconds my patience lasted. Deinstalled it right away thinking there was no point to it at all. Had I only started GPU mining right away... it was hilariously profitable back then.

Took me several month to randomly bump into Bitcoin again and finally understand it's implications.

2.) GLBSE
Peter Lambert and his LIF stuff.
Some other company that I really deserved to loose on.
Zipconf (Still think it was a good idea)

3.) Not selling a single coin in the 2011 bubble.
To buy back at lower prices. Hmm, this one seems to remind me of something............

I can just imagine a this post in six months with people say "If *only* I sold at $134!!" with the price being ~$10

Or the other way round. Unbelievable how people are still buying at 139+$

[GernMiester]

Stopped mining in 09 the same day I started becasue BTC was worthless and I didn't make any coins in an hour or so..

 

[t3c]

Starting in 2010 but then went RTW so couldn't mine whilst away easily
Starting again in late 2011 and realising that i didn't have enough GPU power to hand to make it worthwhile initially
Not buying the 100 coins i would've bought in Oct 2012 had my boiler not blown up that very same week.

Onwards and upwards, 1000 USD a coin soon right? 

[whiskers75]

I thought 'Ah, yay, Bitcoin! I've got 5BTC and I'll go spending crazy.'
~ few years later ~
What!! Bitcoin's worth $141??? AAARRRGHH!!

[Spaceman_Spiff]

I wouldn't call it a mistake, but I started investing $4k dollars in mining equipment and a similar amount in buying BTC directly when BTC was at $8 back in mid last year...
If I invested all 8K in BTC directly, I'd have way more coins!

I am betting some people on this forum would give their left nut to have made a 'mistake' like that.

Trusting anything to be reliable. Mt.Gox's API failed on me at the worst possible time. = losses of 100BTC  well.....

Hope sh*t. Mind to elaborate?

You mean your request wasn't processed by the server?

Loaned a total of 40BTC out on btcjam.  Lost most of it - sad times.  I hate scammers.

[BitcoinTate]

Twice now was I positive that we had hit the top, so I sold.... only to buy back in higher. Lesson learned. lol

[chiliftw]

Trusting shitmarket.eu - twice! The transactions went fine everytime, the users were cool but using it as an online wallet was...expensive... I lost 50 BTC because the admin gambled at first with user´s money (bitcoinica), then got "hacked"
