Not sure how Business Standard has predicted that the crypto tax is not going to change for next 2 years. But there's literally no way to minimise crypto tax in you are dependent on exchanges. Even for P2P transactions, there will be tax.
I think the best way to pay less tax is through gift cards right now. If some relatives are planning to purchase something from Amazon, you take cash from them and give them gift cards. Otherwise there's no straight forward way to save on tax.
It is a possibility as the timeline submitted by IMF on regulation in the G20 summit says 2025 as the year for regulatory framework to be completed. If that is the case then the current tax slab will continue for the next 2 years. I think in that sense Business Standard might have predicted. The government of India has not indicated that they will be coming up with their own crypto framework. Next year they will be busy with the central election. Expect this tax bracket to continue for 2 years with no respite.
