oh there way more tether alt coming one is True USd which is tether reskinned and diff people.
Another coin called carbon coin is coming out:
carbon stablecoin, which is pegged to a value of $1, and carbon credits, which fluctuate in value in order to absorb changes in demand.

When the stablecoin's value falls below $1, an auction is held, and users willing to give up their stablecoins (thereby reducing the supply and driving up the price) receive carbon credits in exchange.

The next time the stablecoin's price rises too high, its supply increases, and those newly created stablecoins are given to carbon credit holders. The process is governed entirely by algorithms.
