Fortunately, I made two Bitcoin trades last week, and the transaction fees returned me 10u, so I have some principal again. I challenged the event contract with a 10-game winning streak, only placing one trade a day, all-in strategy. This afternoon, before tightening the screws, I saw a market trend and mindlessly shorted it; it almost got me killed again, damn it. Thanks to the market maker for sparing my life.
