# Reverse Dollar Cost Average (RDCA)

Like DCA, this fund sells BTC or ETH every day to ensure that the user does not sell all the lowest prices. The user will deposit a token like BTC and over time will get USDT back. Users can deposit less than 1 token but if too small may have an issue depositing.
