USDC is a good way to store your funds as crypto without fear of price fluctuations. It is fairly safe as it's backed by trusted companies like crypto Exchange Coinbase.
What I don't like is that it's only available on Ethereum blockchain, therefore shares the problems of the blockchain such as high transaction fees and low TPS (at the time of writing this review).
USDC is also available on many popular Exchange services which makes trades easier, for day traders and holders who want solidify their crypto holdings in dollar value.
