# Stable Coin Alpha (SCA)

This fund has the same concept but with different tokens. The purpose of SCA is to ensure that the user doesn’t lose any of the principal amount. To do this, the fund gets USDT or other stablecoins and earns interest using staking. With the earned interest, the fund automatically buys a token like BTC and only uses the earned interest.
