You have to evaluate, the reason that you bought the btc in the first place.   Was it because you wanted to be part of something new?   Did you want to be a participant in a vehicle that has the potential to change the financial world as we know it?   Or were you just hoping to double your money in a few days/weeks/months?  Also you need to evaluate if it could affect your life if the value halved again, or even worse.  

If the value plummeting could adversely affect your life, or make you lose sleep, then maybe selling is the best option for you.   If it was the latter, and you want to be a part of the bigger picture, then definitely hold.   There is definitely still the potential for massive growth, it is just starting to look like it is on a much bigger timetable than most had hoped.  

If you bought only a few btc, and your idea was to  get rich quick, then that idea is pretty much out the window for the time being.   That doesn't mean that you are not going to make long term gains on the investment, however.   Keep in mind that a 10-12% return on a stock market investment is still considered strong.  You can still reap those returns on any given day in the btc market.

Don't be in a hurry for your bitcoins to reach their potential value. Will the whole bitcoin economy be worth more than $8 billion in a few years? Many people who understand the technology think that it, or cryptocurrencies in general, will replace a lot of the current global financial infrastructure eventually, which is worth trillions. Will it be a smooth ride up until then? Definitely not. Will it go a lot lower on the way? Maybe. Take a chance if you're greedy, or just sit tight and hold. These forums are full of people weeping about how they were just about the buy back in at $2, $5, $200, whatever. I sold a few at $100 in July thinking it wouldn't see that high again. If you can afford what you have spent on them then hold on to them, if not, sell the bitcoins you can't afford and stop worrying. In the end it's your choice.

Get a back bone fucker. Either hodl or be a pussy, sell and don't ever come back.

HODL!

Alternatively: omg get out, sell, quick, it's gonna crash!!! and besides I need to buy your coins cheaply right?

Summary: it's difficult to take any answer you would get here as an honestly held belief.

For what it's worth: I am not sure which way prices will go when MtGox finally either opens the floodgates or dies outright. I do think that if there's a crash, it will recover. I'm not into tons of risk but I've already covered the amount I put in to bitcoin, so I'll be happy to hold for the foreseeable future and see what happens.

Good luck!

All bitcoin clients are affected by the bug. All you have to do is wait for confirmation after you've made a transaction before you make another transaction.

To clarify, from the linked thread: be careful with subsequent transactions and automatic payments made with Electrum for now.

I once tried explaining mining in a way a seasoned citizen might understand it ... using bingo cards!
