imagine it. Swaps, dexes allow you to change the crypt to another crypt, but there is a problem of liquidity and trust. The user is more likely to choose a binance than an underground service
But on dex, I have no trust problem, because there is no third party. Of course, I understand that for an ordinary person who is new to cryptocurrencies, it will be difficult to understand, unlike the well-known binance. And I dont see anything underground in such a service.
