> 4.6% ? No, sorry, get a better platform
Agreed, but ... is there one? I've been watching the online payments space since the turn of the century, so I've seen a lot of experiments come and go (BuskPay, eGold). I've seen the DotCom bubble and the crypto bubble come and go.
In that time, the digitised credit/debit card infrastructure become - and stayed - the de facto standard for digital payments. A classic example of what Giblin and Doctorow call "chokepoint capitalism".
Almost all of the online payment providers you interact with is backed by one of a handful of giant payment processors (eg PayPal and Stripe, or in China, AliPay and WeChatPay). That are essentially an API between you and the credit card company your card belongs to. That are, in turn. basically APIs between you and the company that hosts your bank accounts.
In other words, companies are squeezing on chokepoints between you and your bank.
