I began trading on Mt. Gox in mid 2011. Having most of my coins on there meant that I could make trades immediately based on market trends. I wasn't aware of all the negative reviews of Mt. Gox, because most of my "bitcoin experience" was visiting mtgox.com every few weeks. As soon as something clearly nefarious was going on, I was lucky enough to get 1.3 BTC out of my account in January. The remaining value of my account was $5000+ USD. I had sent in a photocopy of my passport last November, which they "processed" in February (already aware of the insolvency). This really pissed me off because I was finally "approved" to withdraw USD from my account but I didn't have the ability to do so on the website.
