I understand you are trying to make a positivity out of RBI's stupidity. RBI report mentions a central bank digital fiatcurrency( like the ones considered in sweden, urugway and UK). Countries consider it to avoid printing and transporting paper currency. It has nothing to do with Crypto. Also INR based cryto is going to bring a far less money into market(comparing with USD based cryto) as Indian crypto space is extremely small comparing to the rest of the countries. Instead, simply legalizing Cryto exchanges and taxation will make a huge difference. Also, true cryto enthusiasts will not use a centrelized country backed cryto currency. There are lot easy/wise methods to handle the situation, but RBI didnt do it coz their intention is not in good interest.
