Honestly, you need to research SuperNET/BarterDEX/KMD yourself, it's complicated so takes time to get your head around it, but I'm convinced jl777 has a great product with BarterDEX and KMD. The vision is simple - allow risk free trading of any crypto with 100% privacy, and eventually that'll include XMR.
Atomic swaps are fantastic, but BarterDEX isn't for regular users yet, it works on utxo level, and it's confusing to learn after years of using a centralised order books.
They're targeting the top 1% of high end users who want maximum privacy (no kyc), with no arbitrary limits, and 100% security.
If you're happy to do KYC selfies on regulated exchanges like polo & bittrex you wont ever use BarterDEX, it's a niche service.
