It is actually good that they are using a more well known network other than TRON to issue their stable coin. ETH network has been proven to be reliable for years. Yeah, it is expensive, but not as much expensive right now like you are making it sound. People would rather want to use a truly decentralized chain, instead of using a semi centralized chain like TRON (even though they claim they are fully centralized, if you dig deeper you will know that it isn't). Yeah, its true that more financial institution is using crypto, but its useless because it centralized. We already have fiat for that. Why would be need another central currency?
