You’re forced to put everything on one stock. You have 2 years to substantially grow your money. Which stock would you pick?

If you had to bet everything on one stock and have 2 years to substantially grow your money, which stock would you pick for the best chance at massive upside, and why?

Note: This is a 100% hypothetical scenario, please response accordingly.

This post does not assume you would genuinely do this. If your post reply is simply that you would never do this, then it makes more sense not to participate as the premise of this discussion is that you are forced to choose one stock. Given that assumption, which stock would you pick and why?
