Well it is a really great news that mcdonalds will accept bitcoin because the food will be cheaper and easier to buy. Bitcoins is a digital currency that's why it has a secured and fast transaction and it was really a good idea if bitcoins can be used on a fast food stall.
This is a great news for all the Mcdonalds lovers and also good for those who want to pay in bitcoins for their burgers. The only thing which I think will hurdle them is the transaction confirmations times. Sometimes customers might have to wait for long in order to confirm their payments through bitcoins which can make the queue a bit longer at their shop.
