It is a well-accepted fact that demonetization was a sham at best, a scam at worst.
> So the crypto ban happened during this period and may well of been born out of that initiative against crime.
Again, what peculiar crimes exclusive to India are you alluding to that are suddenly extinct now? The ban was lifted because a successful court petition ruled the government is paranoid at best and out-of-touch with reality at worst wrt crypto.
At least, that is my thoughts upon this.
