The company cooperates with those exchanges with which it was able to agree and draw up a trading agreement. Binance, Coinbase and others, as far as I know, don’t even own the USDT/USD trading pair, so it can’t work with them a priori. Dimax is a relatively young company on the Internet. Because they previously worked offline, they made a good name for themselves in narrow circles, among investors and traders who were ready to work there. The company went online in 2023 and is now gaining tremendous momentum. They have all the documents, licenses and other permits to provide financial services on the Internet. I trust them.
