Bitcoin fell back below $10,000 this week just some two months or so after it peaked in December at roughly $20,000, but panelists at TheStreet's March Trading Strategies roundtable with Jim Cramer aren't interested in "buying the dip."

"If  I can get a real yield in U.S. Treasuries as a safe asset with U.S. dollar-denominated income, I would prefer that," said Brian Leavitt, senior investment strategist for Oppenheimer Funds. "I also like the real yields that exist in a lot of emerging markets. To me, that's tangible. It's something I can feel."

Jeff Marks, senior portfolio analysts with Action Alerts PLUS, Jim Cramer's club for investors, agreed.

"Why invest in something where you can't see a cash flow and where something [doesn't have] true earnings, a dividend -- things like that," he said. "To me, it just doesn't resonate."

And Stephen "Sarge" Guilfoyle, co-manager of TheStreet's Stocks Under $10 model portfolio and author of TheStreet's Market Recon morning newsletter, said he's more interested in stocks tied to bitcoin mining and blockchain than in bitcoin itself, like Seagate Technology (STX - Get Report) and Action Alerts PLUS holding Nvidia (NVDA - Get Report)

"I don't think [cryptocurrencies] are going away, but I do think they will be moved upon by the central banks," he said. "They will certainly lose their authenticity at some point as they are more highly regulated."
