Market making right now is done by Binance with the worst shitcoin called Tether, the former controls almost 60% of the market and the latter is the most traded "crypto" way more than BTC. 
These guys are proposing another solution to a complicated problem that requires either bank accounts and KYC or another type of intermediary, at least they're trying.

I do not see any use case for these so called "stablecoins".
ANY stablecoins is actually a useless shitcoin, just a fancy word for another crap that is linked to fiat money.
