I've literally never heard of anyone using google pay, zelle or venmo or cashapp. My prediction is that whatsapp will add payment functionality too if they dont already have it
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.
