Do you know any of the markets that have executed delistings of these assets?

Indeed I forgot about the Gemini dollar, I actually thought TUSD was GUSD. There is far too much of them and all bare the same attributes but yet none are beneficial in other aspects, the only reason why USDC is taking the lead because it's launched by Coinbase. None of these assets have technological advantages to one another they are all of the same, upon contemplating on the topic I formed a PoC that would create a stablecoin that is much superior to the current implementations and one that fully decentralised. It's going down in the ideas book for sure but I feel there is no gap in the stablecoin market anymore, so idea is quite irrelevant.
