What is even UPI? I don't know and i don't care, if its some altcoin talk about it in the altcoin area. To me altcoins are worthless and you can't change that.
UPI isnt an altcoin. It is a fast (almost instantaneous) way to transfer fiat. You can check the wiki link in my OP.
Unified Payments Interface (UPI) is an instant real-time payment system . The interface facilitates inter-bank peer-to-peer (P2P) and person-to-merchant (P2M) transactions. As of May 2021, the platform has over 100 million monthly active users in India. The proportion of UPI transactions in total volume of digital transactions grew from 23% in 201819 to 55% in 202021 with an average value of ₹1,849 per transaction. Digital transactions worth ₹8.31 trillion were made via the platform in January 2022. In FY 202122, the value of transactions crossed $1 trillion.
I would really suggest having a look at it.
