The price of bitcoin surged more than 15 percent Tuesday and briefly crossed the $5,000 mark for the first time since mid-November. It's still well below the all-time high it hit in December 2017 of near $20,000.
Other virtual currencies saw sudden price jumps, too: Ether and XRP both rose around 7 percent.
Before you start buying cryptocurrency, though, consider the advice of Peter Mallouk, certified financial planner and president of wealth management firm Creative Planning: "What we're going to see, most likely, is, we're going to see cryptocurrencies collapse."
There are so many types of virtual currencies — like litecoin, ethereum, ripple and, of course, bitcoin — that "there's no way that even a fraction of them can survive," Mallouk, who is also author of "The 5 Mistakes Every Investor Makes and How to Avoid Them," tells CNBC Make It.
