Should you buy into bitcoin? Here's what top investors say

Bitcoin crossed the $16,000 mark Thursday morning, less than two days after topping $12,000 for the first time. The digital currency now has a market value of more than $272 billion.

Some of the biggest names on Wall Street are embracing the digital currency, including Fundstrat's Tom Lee and value investor Bill Miller, who is running a fund with nearly a third of its assets in bitcoin.

One Dutch family even bet all they have on bitcoin.

Should you be buying into bitcoin too? Here's what top investors have to say:

Jamie Dimon: Bitcoin is a 'fraud'

The cryptocurrency "is a fraud," JPMorgan Chase CEO Jamie Dimon said at the Delivering Alpha conference presented by CNBC and Institutional Investor. "It's just not a real thing, eventually it will be closed."

He added, at a separate conference organized by Barclay, "It's worse than tulip bulbs. It won't end well."

Michael Novogratz: Cryptocurrencies like bitcoin are 'going to be the biggest bubble of our lifetimes'

"I think this [crypto] is going to be the biggest bubble of our lifetimes by a long shot," the former Fortress hedge fund manager said at a CoinDesk bitcoin conference.

"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."

Novogratz's remarks came right after he gave an aggressive projection for bitcoin: It "could be at $40,000 at the end of 2018. It easily could," he said on CNBC's "Fast Money." And he saw big things for other cryptocurrencies too: "Ethereum, which I think just touched $500 or is getting close, could be triple where it is as well."

Mark Cuban: Only invest if you're prepared to lose your money

According tobillionaire Mark Cuban, it's OK to invest up to 10 percent of your savings in high-risk investments, including bitcoin and ethereum. You've just "got to pretend you've already lost your money," he told Vanity Fair, adding that it's like throwing "the Hail Mary."

Jim Cramer: Bitcoin is like 'Monopoly money'

Bitcoin is a pure gamble, said CNBC's Jim Cramer on "Squawk Box": "It's kind of like Monopoly money. Obviously, there's people who use it. If you ever say anything bad about it, there's like this bitcoin mafia that comes after you. But it is an oddity that has nothing to do with us" as investors.

"It's just pure gambling at this point," the market expert continued. "I mean, if you want to gamble, go to Vegas. Vegas is fabulous."
