In the mad scramble to join the cryptocurrency market, McDonald's have entered the fray with the MacCoin. Celebrating the 50th anniversary of the BicMac, the fast-food chain is offering a limited edition cryptocurrency to burger fans. McDonald's eaters can grab the coins this week from any McDonald's store in America to spend on a free BigMac burger. There is only a limited supply of MacCoins available for purchase but the offer will run throughout the rest of 2018.

How much is one MacCoin worth? In 1968, McDonald's launched a two-patty burger that catapulted the brand into the public conscience. The BigMac has become synonymous with fast-food and has become almost as recognisable as the “Golden Arches”. To celebrate the birth of one of the world’s most popular burgers, McDonald's is launching its own cryptocurrency. More than 14,000 McDonalds restaurants will be taking part in the scheme to bring customers back to the fast-food chain.

McDonalds have entered the fray with the MacCoin.

As of August 2, McDonald's fans will be able to secure a MacCoin when they buy a BigMac. Unsurprisingly, a MacCoin can then be used to buy another BigMac at participating restaurants. This means the price of a MacCoin will stay the same price - what ever the cost of a BigMac is in your area. McDonald's has said that more than 6.2 million MacCoins will be available across US restaurants from Thursday, with the offer running all the way to the end of 2018, or until the MacCoins run out. Last year, the Burger chain sold 1.3 billion BigMacs so it is easy to see why they made the decision to dive into the cryptocurrency world.
