Burger King introduced its own crypto in Russia, ladies and gentlemen, meet Whoppercoin!: https://www.theverge.com/2017/8/29/...currency-whoppercoin-blockchain-trading-waves "A supply of 1 billion Whoppercoins have been issued so far, and customers will receive one Whoppercoin for every ruble spent ($1 is 59 RUB). They can redeem one Whopper burger with 1,700 Whoppercoins, which are stored in a digital wallet. While the Whopper cryptocurrency is a bit of a gimmick, customers can still trade and transfer the coins, just like any other cryptocurrency." As far as I know, this is the first crypto introduced by a big retailer/chain. http://www.wavesgo.com
