USD coin is a stablecoin more known by its ticker, USDC. What makes it stable is that every coin is backed by, you guessed it, 1 US dollar. As such USDC might be a perfect investing opportunity for those who doesn't dare to dive right into the deep end of the crypto pool, but prefer to have something solid and, well, stable to keep afloat. To make your investment even more secure, you'd better use as much data on the coin as possible, and this is where we can help — we've calculated USDC market cap, that is its number of coins in circulation times their current price. The line's upward direction might indicate investors' confidence in the digital asset, while the line going down might be a red flag for traders. Still it's always up to you to do your own research.
