Finally. Sheeeit. I arrived in China in I think 2016, and the whole country had already transitioned to using QR codes. Merchants actually rejected cash when I tried paying in cash. Wild. But it immediately became clear that payments via QR code would become the norm everywhere, and whichever currency did it first would win **_all_** payments. Bitcoin has moved irritatingly slow. So slow, it seems like it must be being actively hindered.
