Build Trust & Stability with USDC On Stellar

1️⃣ Promote USDC as a Stable, Safe Digital Dollar

Unlike Bitcoin, USDC is a stablecoin pegged 1:1 to the USD—meaning no major price fluctuations.� Use simple messaging to educate users:

  • “USDC is digital cash, always worth $1.”

“No volatility, no risk—just a safe way to send and receive money.”� Compare USDC to local currencies that lose value due to inflation (e.g., Naira, Shillings).

2️⃣ Educate Users on Crypto Safety

Run awareness campaigns on social media, WhatsApp, and local events.� Teach users how to avoid scams, such as:

  • Never share private keys or wallet PINs.

Only use trusted wallets and exchanges.

Be careful of “investment schemes” promising quick profits.

Increased adoption, as people see crypto as a reliable financial tool, not a risky investment.
