I've heard that in the U.S., the term "Venmo" has become a verb meaning to transfer money.
Similarly, I suspect that "ZAP" may evolve into something different from the meaning of giving a tip, possibly being used as in "paying with ZAP".😂

I thought of having my American friend, who came to visit Japan, make a Bitcoin payment through CashApp. But it didn't work. I wonder if it's not supported in Japan?🤔
