Could be. I used PayPal to transfer money to friends before it was even accepted on eBay, but obviously that's a pretty niche example. It looks like Venmo is ~2x as popular as Square Cash from this recode article: https://www.recode.net/2018/2/27/17059182/square-cash-app-monthly-active-users-customers-seven-million-december-venmo https://www.recode.net/2018/2/27/17059182/square-cash-app-mo...
