Steem-based crypto exchange?

Bitcoin is already 10+ years old and we already have 3000+ cryptocurrencies trading on 250+ crypto exchanges out there. Fewer exchanges offer fiat deposits due to legal and security risks, some prefer BTC, because of its first-mover reputation, some use ETH because it's the main token platform, recently I've even started noticing XLM and XRP as the main trading pairs. But since crypto doesn't have enough stability yet, most people still prefer using USD pairs, so we have USD-backed cryptocurrencies here like USDT/TUSD/PAX, but there is also a problem with getting those coins/tokens since the verification process is not simple at all and requires a lot of personal data...

But what about Steem Dollar? It's fast as Stellar and Ripple, but at the same time, it's decentralized and showing great stability for last years. And unlike other crypto-fiats, it's much easier to get.

What do you think guys, wouldn't be cool to have a steem-based crypto exchange? Would you use it?
Also, maybe there is already one, but I couldn't find it?)))
