The Time Travel of Money

Flashstake allows anyone to buy, sell, and earn the *future* value of their money, *today*. To time travel with your money, all you have to do is follow three simple steps:

1. Choose the **amount** of tokens you want to stake.
2. Choose the **duration** of time you want to time travel into the future.
3. Instantly and **upfront**, receive the future value of your money, today.
