Well, McDonalds is a one of the largest business and fast food here in our world. I think that McDonalds saw the price of Bitcoin and they wanted to have more of it in able to gain more money. Because if they will hold a lot of Bitcoins, They will gain a lot of money time to time. Because as the time goes by, Bitcoins are getting higher on its price. McDonalds will also helps Bitcoin to be popular in all people here in the world. And assure that many companies will also accept Bitcoin as mode of payment soon.
