Sorry- what's the connection here? Libra will apparently be a basket of different major currencies, how does this benefit the US specifically? I say this as someone who would like to preserve dollar hegemony, I just don't see the connection
Social network payments will be a "radical monopoly," and the ability to manipulate exchange rates on that platform gives absolute power over import/export prices. Probably not something you want to yield.
If you’re using a credit card as source payment, you get a bank to protect your purchase and presumably some points or rebate?
I understand cryptocurrency as potential replacement to wire transfers and cash payments. But as a consumer friendly choice, why would somebody choose to pay with crypto over NFC pay (with banks promising purchase protection when coupled with credit card)?
