So far I don't see a lot of effect of this thing on the daily volumes of WazirX, if you see the highest volume pair that is the BTC/USDT, there was a sharp selling volume on the 31st when the provision was to come into effect, but after that since last two days volumes have been pretty much decent, here is the image of the BTC USDT pair chart

and I see volumes in March even more than what we were having around Feb end and march beginning, Also the INR/USDT pair is trading at a premium as compared to dollar which too is a sign that the Indian market isn't dried up so far. Let's see what happens in coming days especially after the TDS provision kicks in which looks really draconion.
