Finally, I think that if a large business like McDonalds starts accepting payments with Bitcoin or other cryptocurrencies this information will be announced quite quickly through reliable sources. For this reason, I think this content isn't accurate as there are many questionable details about the current situation and it has not been verified by any reliable source.
Indeed. Also, I'm not quite sure the way how McDonald's could accept BTC since it is a fast food chain and the order should be paid fast as well and this is how you can spend a few hours in McDonald's just waiting for your transaction to get confirmation as none of the solutions (such as LN) was mentioned on the screenshots from the first post.
