0.2% should be about the correct rate. WeChat in China has zero transaction fee in the system and a 0.1% fee on withdrawals. Visa/MasterCard amounts to a private tax on the economy. Unfortunately I don't see this changing anytime soon, since the US allows rent-seeking middlemen like Visa/MC, TurboTax, and PBMs (pharmacy drugs), to continue their operation as long as they keep funding the right politicians.
