I bought 4 BTC on Mt.Gox when they were ~$25 each. Naturally, after I bought it crashed to the ~$1 territory. Thought to myself "Figures..." and decided might as well hold. Cut to a year (or two?) later and the prices hit the ~$30 territory. I decide to sell and reap a nice little ~$20 profit. Lucky me, eh?

Tangential to the current discussion but you didn't have to cash out, you just had to transfer the coins to your own wallet. I think that was the only reasonable choice -- IMO it really seemed at the time that storing coins with mtgox was not a trustworthy option.
