Over $1 million in bitcoin was hidden in a picture – and there's still some left to be found.
Called the 310 BTC Bitcoin Challenge, a pseudonymous user going by the name "Pip" stashed a total of 310.61 BTC (worth $2,011,267 at press time) into four digital wallets earlier this month – with the recovery code for unlocking each wallet decipherable through careful investigation of a single black-and-white image.
It's a familiar concept within the space. Earlier this year, a crypto enthusiast won $50,000 worth of bitcoin by solving a puzzle in a painting called "The Legend of Satoshi Nakamoto" by visual artist turned blockchain developer Marguerite deCourcelle.
