There’s a new superhero in San Francisco who is creating quite a stir by “donating” hundred dollar bills to whoever finds them by following the clues left on Twitter.

Their Twitter account Hidden Cash provides the clues necessary for finding the cash, which is hidden somewhere in the San Francisco Bay Area, and the whole thing is open to whoever would like to take part in this bold social experiment with cash prizes.

There’s a lot of speculation around who this mysterious benefactor actually is, but according to an interview with the Bold Italic they’re a real estate mogul who has made millions from the Bay Area housing market and just wants to give back to society, and they’re planning to hold a “huge giveaway” once they reach 100,000 Twitter followers. Game on!
