Others are not fans at all. JPMorgan Chase CEO Jamie Dimon called bitcoin a "fraud," adding "it's worse than tulip bulbs. It won't end well." Billionaire investor Howard Marks called it a "pyramid scheme."
And then there's the camp occupying the middle ground, who don't say it's the best investment, but also don't say it's the worst investment.
Billionaire Mark Cuban seems to be among that group. As he told Vanity Fair, 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 said, adding that it's like throwing "the Hail Mary."
Tony Robbins has his own analogy for investing in bitcoin: It's "like going to Vegas," he told CNBC's "Fast Money."
Cuban and Robbins advise only betting on what you can afford to lose. If you win, great; if you don't, at least you only lost discretionary funds.
As for the best way to invest your money right now, go with a cheap S&P 500 SPX fund, says Cuban.
