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

[mobodick]

Putting most of my coins in Bitcoinica (SCUMBAAAAAAAGS!!!!)

[t3c]

Unless they hit 100K a pop i am never selling

....although if that happens >...

Not sure it applies since it's more related to the bitcoin community than bitcoin itself, but https://bitcointalk.org/index.php?topic=161710








vvvv LOL Priceless.

Not exactly in the theme of this thread, but I once sent 10 btc to the wrong address by accident. I Google'd the address and it turned out to be Gavin's. He sent them back to me

Lucky break!

organized lending.

Worst mistake was trusting MtGox with my bitcoins. Lost pretty much all i had back then due to this lame vulnerability on their site.

[mr-sk]

Lost a bunch of BTC on tradehill and never could get it back. Also lost BTC on the 1st mtGox hack.

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

I have thought about selling a number of times in the last few days, but each time I wake up and check the price on mtgox I end up quite happy that I didn't. I think I am just going to hold indefinitely regardless of what the price does, and when more and more shops begin accepting BTC i will use it for its intended purpose - as a currency.

Back when coins were around 10-15 I gambled some BTC at Bitzino. Playing blackjack I went from 6 BTC to 14BTC in 2 days. Could have stopped there, but pushed my luck. Lost it all within a couple minutes. Martingale betting is fun and profitable for awhile but it will bite you in the ass if you get greedy.

Back at the day when I was new to bitcoins you could buy them at about 6$ per coin, wish I could travel back in time and slap myself on the head and invest all I can gather into them.

not starting early enough

[xqr]

So far my biggest mistake has been ordering a Jalapeño with BTC. I probably won't see the hardware for at least 6 months, woulda been better off just hoarding the BTC I used to pay for it.

Second biggest mistake was using bitinstant to transfer. My money has disappeared.

[deathcode]

not starting early enough

I sold 9.5BTC at $2000 yesterday when they were $189...
Today even though I sold at an avg of $210, I'm losing money.... :/

I'm not selling until I reach my goal!

#1 mistake.

Back when bitcoins dropped to 3$

I stopped my mining rig and upgraded my main pc with the parts.

If I didn't stop mining, I would have made way over 35 bitcoins.
Probably up to 300 bitcoins.


#2

I sold my bitcoins for... 23$
Made 700$, reinvested half in a new mining rig.

Now I got 3 bitcoins.


No losses at all, just fun... and hell of a facepalm thinking of the money I could have made.

[gollum]

Biggest mistake: invested a big amount in gold and silver instead of Bitcoin six months ago. That investment would be worth 20-25 times more now.

[oOoOo]

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"

Same. Although I only trusted them once, and "only" lost 40 BTC...
I'll get dizzy now thinking of how much it is now.

They did not only steal my coins, but also a part of my future

biggest mistake:

not buying in when i first heard about it!

[Dangolbery]

Knew about Bitcoin since it was at about $2, never bought any as i was poor uni-student
Mined with my old computer, before mining pools, but turned it off after a couple days because it was going to take about 5 months (average) to hit a block (get 50 coins). Would have a couple hundred at least if i let it run, for no real cost to myself.
Got 5 coins from Bitcoin faucet way back when, which i just left in a wallet to rot on an old hard drive that i dumped when i threw out my old computer.
At the start of the most recent boom, @$30/btc, i signed up to mt.gox (thinking it was the only real way to buy mass coins - stupid) as i wanted to buy $2000 worth of coins. Waited about 3 weeks for my account verification so i could fund it, verification got rejected and Bitcoins tripled in value.

Ended up getting my $2000 worth of btc's at $96 a piece on localbitcoins. The thing is i looked at localbitcoins while my account was pending verification and thought it look a bit shady so continued to wait for mt.gox while the price skyrocketed.

My bitcoin experience is full of missed opportunities, however i have my coins now and am happy. If the price continues to climb i have a stake in it. If it plummets then i simply have the chance to buy more.
