Some virtual currencies are getting narrower focuses on individual categories, and Burger King has applied the concept to Russian fast food.

The chain's WhopperCoin has debuted in Russia back in August, according to Waves, the distributed ledger network that is powering WhopperCoin.

With each purchase of a Whopper, customers receive WhopperCoin tokens through a digital wallet. These reward tokens can eventually be used to purchase Whoppers once the customer has collected enough coins. The tokens can also be transferred and traded online, so customers can sell them to new buyers.

"Now Whopper is not only [a] burger that people in 90 countries love. It's an investment tool as well," said Ivan Shestov, head of external communications at Burger King in Russia, quoted in the Waves release. "According to forecasts, cryptocurrency will increase exponentially in value. Eating Whoppers now is a strategy for financial prosperity tomorrow."
