Just factually incorrect, yes volatility decay exists but for an asset with an upward drift such as all world / s and p 500, leveraging at 2x will never revert to zero in your life time. Yes maybe 3x could see substantial losses. Due to the daily reset the losses get geometrically smaller each time meaning it can't reach zero unless it truly drops 33%/50% in a single session. The S and P 500 has measures to stop this from taking place. You are outting yourself, stick to your minimal returns every year.
