Could you explain in more detail how to pay using Bull Bitcoin wallet? I set up the wallet, entered my phone number, registered, then found their internal page (SINPE Móvil) in the wallet for Bitcoin. But when I went there, it said either you're a registered user or you're creating a new account. I registered inside, confirmed my email, but now it also says to confirm the phone and so on. Did you do all this or not? Because you mentioned that registration isn't always required. So how did you pay then?
