In simple terms, the official website $USUAL uses everyone's staked money to buy U.S. Treasury bonds, which has a major issue.
The more money that is staked, the lower the interest APY offered, eventually reaching a balance point.
However, if the money earned from U.S. Treasury bonds is less than the interest at this balance point, then the staked individuals will not be able to retrieve their money.
To fill this gap, the issuer may have to deliberately make the coin's price fluctuate to siphon money from everyone.
But by doing this, everyone's confidence in the coin will surely be lost.
This is just a personal opinion.
