Former Fortress hedge fund manager Michael Novogratz told a conference Tuesday that the digital currency market will be a wild roller coaster ride full of froth and shady behavior.

"I think this [crypto] is going to be the biggest bubble of our lifetimes by a longshot," he said at the CoinDesk Consensus: Invest conference in New York. "To be fair, this is a bubble and there's a lot of fraud mixed in. We look at tons of projects. And some get funded, and they literally look like Ponzi's. There's a lot of froth and fraud in something that's exciting as this."
