As ERC20 And TRC20.
Tell me about it.
Much could be said about it, such that Tether would enter a market that was dominated by only a few, such as Karatgold. The only question is whether you can exchange the new "TetherGold" for real gold and how.
But one thing is clear: Tether could produce gold with just 2 clicks.

100% either a scam or a misunderstanding since it is impossible to have a gold backed "Tether". Learn from history, have you ever heard of the "Liberty Dollar"? Warehouses full of gold get raided by the Feds. Simple conclusion: ERC20 and/or TRC20 backed by pure BS.
This seems to be a reality soon. Official site of Tether:
