Some of the coins like USDT and USDC are the leading stablecoins in the market and people rely on them, but you never know if something wrong happens and we might end up losing our money.
That's because they are dependent directly on the macroeconomics of USD, so they have an exposure equal to that of USD's risk.
In that context....HBD is truly a decentralized Blockchain-based stablecoin that is not tied to the risk exposure of USD. And that's the difference between the two.
