You get to see one crypto price at any time in the future: What coin and what date do you choose?

Imagine you have a one-time opportunity to peek at the future price of any single cryptocurrency on a specific future date. Which cryptocurrency would you choose to check, and on what exact date? Remember, this unique chance allows you to see only the price of your chosen coin on that particular day, without access to any other price history or graphs. It could be Bitcoin on an important date in the future, or perhaps a different cryptocurrency at a crucial moment.

How would you use this information, and why would you choose that specific coin and date?
