As you said I won't suggest the tax evading but it can be avoided with right strategies like transferring the funds to different user's account like family and relatives that we can trust.
This might be a good idea. We can always keep funds diversified in multiple accounts which might be of our family. But we can still pay regular minimum tax amount just to get ITR clear and we can still wager funds using other accounts.
I'm hoping so see local merchants accepting cryptos or helping exchange them. Not in all cities but atleast Tier 1 or Tier 2 cities should implement this. I remember there was a bitcoin ATM here in Bangalore setup by Unocoin but it was closed. The only operational now is in Delhi I guess. Such ATM's are much easier to anonymously convert btc to cash.
