Thanks for the story! One of my first steemit entries was about an ill-fated attempt to run an international arbitrage on MtGox before the exchange went belly up, and I'm planning a follow up post in the near future going over EVERY.DAMN.TRADE that ever went against me. I've been keeping a list of them over the last 15 years, I think now's the time (and steemit's the platform) to tell those stories!
