Yesterday, I was looking at the 59.5-64k range and had a sudden idea. I wanted to simulate shorting volatility and shorting gamma using contracts. So, I set up a neutral grid on $BTC at 59.5-64k with $2M on OKX @okx, using 20x leverage (total $40M position). The annualized return hit an astonishing 3000%! But during that pump this morning, I was down as much as $500K at one point—scared the hell out of me. Luckily, I had enough margin. This is basically the same concept as a short straddle in options. I set stop-losses at 58.5k and 65.5k, though adding a call and a put at the tails for protection would’ve been even better. In the end, I closed with an $85K profit. The professor just completed a great experiment with $2M!
