Boost your rewards by inviting friends to join Micro Node through our **Cluster Reward** system! Here’s how it works:

1. **Invite Friends and Unlock Cluster Blocks**
   * Share your referral link with friends, and each successful invite earns you a **Cluster Block**.
   * Cluster Blocks can boost your earnings by up to **50 USDT** per invite!
2. **Earn a Cluster Booster**
   1. Each referral adds a **Cluster Booster**, increasing your reward score with every interaction.
   2. The larger your Cluster, the higher your potential rewards!

*Tip: Each Cluster Block opens up new reward possibilities—keep inviting to multiply your rewards!*
