- **鸟枪换炮 · 2026-07-09T14:58:44.000Z**: It has to keep rising; if it goes up one day and down the next, it'll end up at zero.
- **Mr.Light · 2026-07-09T14:03:14.000Z**: If it's less, it's at least 17-180. If the underlying stock gains 10 points tomorrow, it will hit 120, corresponding to a stock price of 240.
- **数字游民 · 2026-07-09T14:01:38.000Z**: Not only that, continuous small gains have a compounding effect.
- **迷雾溪流 · 2026-07-09T13:56:23.000Z · 👍 1**: Let's see how it rises. It's like a 50% increase in one day means doubling is a 100% increase. Four consecutive days of a 10% daily increase means doubling is over a 100% increase.
