Dogecoin creator Billy Markus has added a new token to his NFT series, titled "Crappy Dogecoin Doodles." featuring a swiftly drawn Shiba Inu dog lying in a field. The NFT is currently auctioned for 0.069 ETH ($140); Markus will take only 10% of that. Four hundred twenty copies of the token will be up for auction until the sale ends next week.
