# How Does Auto-Staking Work?

* The SAP Auto-Stake feature is a simple yet cutting-edge function called **Buy-Hold-Earn**, that provides the ultimate ease of use for $SPRO  holders.
* **Buy-Hold-Earn** - By simply buying and holding $SPRO token in your wallet, you earn rebase rewards as interest payments directly into your wallet. Your tokens will increase **every hour.**.

Using a Positive Rebase formula, StackPro makes it possible for token distribution to be paid directly proportional to the epoch rebase rewards, worth 0.03% every 10 minute epoch period of the total amount of $SPRO  tokens held in your wallet. The rebase rewards are distributed on each EPOCH (10 minute rebase period) to all $SPRO holders.<br>

**This means that without moving their tokens from their wallet, StackPro holders receive an annual compound interest of 200,000%.**\ <br>
