There's been loads of these and they're each as pointless as the last as none of them offer a single incentive over Bitcoin or indeed fiat money to anyone.
Dopecoin, Cannabiscoin, MaryJcoin, Weedcoin just to name a few. Every year in mid April they rise in price because idiots buy them thinking that bigger idiots will buy them on 4/20 because obviously that's what stoners do on 4/20, they spend their money on cryprocurrencies named after cannabis...
