Some people in my circle have already switched to Cash App from Paypal, though the drawback is that not much people knew about Cash App and its wonders and are still stuck on using either Apple Pay (which sucks btw) and Paypal which, of course is handy for its chargebacks.
Actually, CashApp has been one of the top financial applications in the US App/PlayStore for quite a long period of time now. In other words, plenty of people know about it.
I wish they were offering their services within my country, but unfortunately they don't. I read somewhere that they were planning to roll out their service within Europe, but that can take a long time if it isn't their main priority and their licenses haven't been granted yet. I like to side with businesses that are building on top of the right coin and have the right intentions.
