Bitcoin won't be the official medium of exchange in cashless society. The future form of money is CBDC, not Bitcoin.
we dont know if that cashless society is true so its okay if btc is not the official coin for that and there are currencies that can be more of a candidate on that field but i dont think its your coin because i havent heard of that coin your promoting but it can be included on the future of money when it showed its worth .
Needless to say, the credibility and acceptability of Bitcoin is growing day by day; At the same time, its value has also increased.
its price wont grow if not because of acceptance and being credible . the three elements can be a gateway for btc to have a bright future .
