After LUNA hyped, I think that it is better for platforms that provide staking services and for investors to stay away from investing heavily in stablecoins in order to achieve easy and quick profits.
The principle of proving staking in these currencies has proven that it has a point of failure and then the return is like 8 and 10 you will lose if the link between these coins and the value of 1 dollar is broken.

So I don't think this is good news, especially if Coinbase stock investments was bad and the cryptocurrency start a bear market, how will USDC be able to pay the 8% APY?
