But you use Twitter..? That's some crazy bubble. venmo isn't even a tech savvy thing, everyone everywhere I know that moves money between individuals or super-small business transactions (think cleaning service, girl scout cookies, club dues) uses it...
I'm banned from Cash App so I use PayPal as my primary bank.
UPI makes sending and receiving money as easy and instant as sending a text, that I can not believe how the rest of world lives without it. Free account to account transfers (upto ~1200USD/day) that work from any bank to any bank, in seconds. Even accessible without internet via ussd short codes.
