Billionaire Mark Cuban recently revealed that the worst investment deal he made on 'Shark Tank' was Breathometer. Cuban invested in the smartphone breathalyser after Charles Michael Yim pitched the idea in 2013. "I'd look at [Yim's] Instagram and he'd be in Bora Bora...Two weeks later, he'd be in Vegas...Next thing you know, all of the money is gone," Cuban said.
