Your biggest bitcoin regrets?

[600watt]

biggest mistake was that i thought mtgox/bitcoin was scam and shoved it all into the garbage bin after purchasing 100 btc in june 2011 shortly before bubble burst and my mtgox account got hacked.

in the 2nd half of 2011 i happened to have 30 k € to invest. choosed gold & silver.

so i actually was on track to make a fortune but got discouraged so deeply that i forgot all about this "scam".

Since first hearing about bitcoins in October 2011, I have spent around £7000, give or take, on various mining adventures. GPU rigs, an AM blade, a yet-to-arrive BFL single, AM shares, an aborted big buy of Klondike boards with Avalon chips... I've done it all.
I'm currently sitting on bitcoins worth maybe £20000.

By any non-bitcoin measures that's a fantastic investment. But my regret is, well exactly what you'd expect. WHY oh WHY didn't I just BUY the fucking bitcoins?

(insert pathetic self-backpatting rationalisation about 'helping secure the network' here)

Turning off CPU mining from my laptops because it would take over a week just for one measely block of only ฿50.

Buying a pizza for 10000 bitcoins

Looking at that transaction, the guy had a lot more left over  

Not buying back in at $60

They'll be saying that next year about not buying at under $150.

But we have to look back. It improves our future.

Just enough to learn from the past. No need to dwell. I prefer looking back on other people's mistakes so I don't repeat them. Most stupid shit has already been done.

Very true. Sometimes though, you just have to learn the hard way.

But my regret is, well exactly what you'd expect. WHY oh WHY didn't I just BUY the fucking bitcoins?

If it's of any consolation, back when GPU mining was still a thing, the future of bitcoin was so uncertain that if you'd bought $1000 of coins and BTC crashed, you'd lose it all.
If you'd bought $1000 of computer parts, you'd at least be able to re-sell them. So mining was the less risky option

Lol. The pre-gpu days were pretty neat. We had so little clue about what was going on. But Satoshi's gentleman's agreement to keep away from gpu mining meant that ฿ got widely dispersed to lots of people. Having a wide user base increases the odds of getting sufficiently talented people sufficiently motivated to finish the work of getting the network off the ground. We are still not done yet.

it hurts but i can add to this list:

turning on my laptop 3 hrs ago.

Sending 25 bitcoins to the wrong instawallet address. Dumb dumb dumb.

I swear I double check the address every time I send BTC, but then get paranoid after sending and check again (so far correct every time!)

[EvilPanda]

Not knowing anything about BTC a year ago 

[super3]

1) Pussying out of spending $1,000 to buy a decent amount of Bitcoin a year ago.
2) Not trying hard enough to get litecoin mining working before the megabubble.
3) Turning my Bitcoin miner off because it was noisy during the GPU days.
4) Not cloudmining Primecoin the first week it launched.

Buying some BTC lastnight before this massive crash....

[crazy_rabbit]

not buying more.

[hulk]

Got scammed from BFL and do nothing from the recent silkroad crash.

[mmitech]

lost over 13BTC at $260 bubble, and around 20BTC at the silkroad news, I sold at $98 wanted to buy back at $85 but I was thinking it would fall even more so I waited, sadly the priced recovered in less than 30 min, I didn't want to buy back at $106 and $115, then when I knew that I fucked up, I bought back at $121.

I worked hard to earn that BTC and I squeezed every possible chance to get more, then at a fear moment made the wrong decision and lost around 30BTC.

After learning about Bitcoin when it was $0.80 I tried to buy 10 and gave up. (WTF)

I solo CPU mined for 3 months and never found a block. (Waist of valuable time)  

 Buying shares in a mining stock that ran away with my Bitcoin.

After pool mining my first 10 Bitcoin I sent it to one of the top 100 richest Bitcoin address by mistake when trying to purchase a few Casascius coins. (Never just cut and past an address without checking and you can always make mistakes)

Actually buying 1 physical Bitcoin with 2.5 Bitcoins (combined with the mistake above each Casascius coin cost me 5 Bitcoins.)

Selling 2/3 of my coins at an average of $13

Telling my wife how many Bitcoins I sold @ $13 when they were trading @ $260

No unanticipated losses, particularly since my spending money in Instawallet was eventually returned.  Trajectory on target for a decent win in the end.  No real regrets so far except that I've been to lazy, fascinated with the price rise, and focused on how I might capitalize to take the time to really understand the system in a deep technical way or make any contributions.

Giving up trying to wire money to Bitstamp when my bank simply refused to comply (after blocking my account twice) in early 2012, trying to buy more Bitcoin. I'm still a customer at that bank ...
