Don't forget those options aren't just lottery tickets; unless your employer is giving out options with 10-year exercise windows, they're rigged lottery tickets. viz the CTOs on here talking about using them as retention leverage.

You can find a (very small) list maintained by Zach Holman here: https://github.com/holman/extended-exercise-windows

I assume Zach got interested because he discovered after he was fired from github that he was close to losing all the money he "made" on options when github became a unicorn -- he probably had 90 days to exercise a very high priced illiquid security with horrid tax consequences if he fucked up. That's the thing about cash: it's not rigged. If you get cash, it stays in your bank account. Paper gains can disappear.
