I came accross this little gem a while ago .. my buddy introduced me to it when it was stil in the beta stage .. at this point thw Nimiq browser miner is up and running .. Nimiq gives everyone the opportunity to mine cryptocurrency (NIM) using just your cpu.. even using one core , one is able to mine whole coins .. at this Point the coins arn't worth to much .. but this is certainly a platform that holds great interest in my eyes..
Check out this Nimiq browser based PET. .
Yup , mine nimiq and mine food .. feed your pet once a day so that he doesn't die .. he could be worth alot one day !! Enjoy!!!
