Not sure what happened to coinswitch but I don't think it deserves to be on the list of instant exchanges anymore. The whole layout is now different. More like regular exchanges where you purchase or Bitcoin for fiat and vice versa. Like how coinbase.com operates.
I don't see the feature to instantly exchange crypto to crypto like it used to be.
They used to be an
aggregator where you could see offers from multiple exchanges (both instant exchanges and CEXes like Binance, Hitbtc, etc.) but it appears that they're no longer offering that functionality. As you said, they're just a fiat exchange now (for Indians only). Thanks for letting me know, I'll remove it.
