I know about crypto and everything in general but I am having difficulty to understand one thing about it. Why crypto or bitcoin is better than money ?

I mean I know the block chain technology is revolutionary and it has many benefits, it is being used by all crypto. Money is used to buy goods and services and there are very less businesses accepting crypto and still the prices are rocket High.

This Crypto trend looks more like share market company evaluation rather a legitimate currency. Moreover all government have there own currency, goverment cannot let that sink and can ban these. Can someone explain to me the value of Crypto as a currency when compared to real money ?
