When it comes down to it, none of us know what the real truth is concerning what has happened. We probably won't know for months, and that's assuming we're lucky enough to have it all come out into the open. This whole incident has been one huge fiasco that could have and should have been handled better by all parties involved.
People writing long drawn out posts, providing chat logs, and speculating wildly is doing nothing for Bitcoin as a currency. Short of providing entertainment for a few and food for the trolls, it certainly isn't productive. We should all know by now that you can't trust anything on the internet. As such, let's all take a moment to relax.
Where should we go from here? For the time being, keep yourself advised on how the recovery process is going at Mt. Gox. If you had money in either BTC or USD at stake there, make sure you're doing your best to work with them and recover your account ASAP. If you no longer trust them, take your money and go. If you do still trust them/think they'll do better now, stay and begin to trade when they open back up. In the meantime, consider using alternative exchanges to continue your trading.
This campaign of FUD across our forum is unnecessary at the very least and is more than likely harming not only the Bitcoin as a cause, but for those of you looking to turn a profit, it is harming the value as well.
Let's move on and let those involved sort this out as best they can.
