El Salvador’s recognition of Bitcoin (BTC) as legal tender has opened up new payment options for its citizens, with fast-food empire McDonald’s reportedly accepting payments in the cryptocurrency through Lightning Network.  Journalist Aaron van Wirdum broke the news Tuesday after he visited a McDonald’s restaurant in El Salvador, where he was presented with a printed QR code directing him to an invoice page on Lightning Network. McDonald’s had 19 locations across the Latin American country as of 2019. Just walked into a McDonald's in San Salvador to see if I could pay for my breakfast with bitcoin, tbh fully expecting to be told no.But low and behold, they printed a ticket with QR that took me to a webpage with Lightning invoice, and now I'm enjoying my desayuno traditional! pic.twitter.com/NYCkMNbv7U
