Cash App looks very promising.Paypal gets worse every year,with their constantly increasing fees and incredibly weird policies.If you are a business owner accepting payments via Paypal,they basically own your money and you are their slave.It's good to know that PayPal's competitors like Square gain recognition and try to expand into the crypto world by accepting Bitcoin.
In my country, PayPal is not popular, because we have super-weird limited access to it. We can send money via PayPal but we cannot receive it. It's good that the alternatives are appearing because perhaps countries like mine would be able to adopt it instead of PayPal in the first place. For now, however, Cash App is extremely limited and, if what I read is right, is available only to people in the US and the UK. Moreover, the app only allows sending money within a country, no international payments are available. Apart from that, I am wondering how it deals with the US taxation system which some claim calls for tax payment every time a crypto-to-fiat (or even any crypto transaction, Idk) transaction is made, which sounds ridiculous.
