There is a valid case where crypto will occupy the place of black-money in countries like India. There is a minimum rate fixed by the government, especially for land. But the market rate is (many times) a multiple of that rate. So when you buy land, you pay the minimum government rate (plus tax) so you can enter into ‘legally binding’ sale agreements. The rest you pay in crypto. In other worlds fiat currency issued by governments will continue to the extent of the legal sanctity they provide to any transaction. The rest is crypto.
