Yes "Gods own country"

, i will tell you this, it is not illegal to run crypto based business ..
Then you are misinformed. According to RBI rules no business is allowed to commercially exchange cryptos for Indian fiat. Ask the Unocoin guy. Or the Koinex team or even Zebpay.
How can you run a business with something that is not recognized as a form of payment? You can't pay taxes, the Tax dept would be out to get you and you'd be fucked.
Do you know how traders blackmail on Bisq? Once I tried trading and some dude wanted me to pay first without him showing any signs of the btc that he was supposed to sell. Long story short it ended with him calling me up (thank you for exposing my number Bisq) and says he'll file an FIR against my name saying I am engaging in ML just because I did not want to pay him first. I handled him, taught him a proper lesson. But everyone's not like me, especially us Indians are prone to getting duped.
Long story short, Bisq will not get to the levels of LBC in India.
With a small community of buyers and sellers, you need all the sellers in as few many platforms as possible to maintain competitive rates - we're already paying 9 - 15% premium to buy / sell crypto, that would soon multiply otherwise. That's why we should stay away from fringe websites that add no value to the community and subjects traders to scam attempts.
So I'll repeat, there are no viable alternative to LBC or LETH with exception to Wazirx.
