In Manhattan, a cup of coffee will set you back about $2. Or .00098 Bitcoin. Or—here’s a new one—12,500 NewYorkCoins.

Never mind alternative currencies such as Tigercoin, Ethereum and BiblePay. There’s a cryptocurrency named for our fair city, and it’s gaining momentum.

Last week, I met two of the coin’s volunteer boosters at Gila’s Nosh on East 23rd Street, one of several local businesses accepting NewYorkCoin as payment.

James Burrell, a high-energy business lawyer, and Charles Fulnecky, a low-key developer, explained the currency’s features.

Transactions are confirmed in 30 seconds—20 times faster than Bitcoin, they said. And there’s no network fee on small transactions like buying groceries, making it ideal for daily use.
