Thomas Lee, head of research at Fundstrat Global Advisors, said the bear market for small-cap cryptocurrencies is over. But he said he still thinks bitcoin is the best bet for investors.
"Increasingly, I think investors are comfortable that bitcoin is likely to be viewed as a commodity," Lee said Tuesday on CNBC's "Fast Money." "Whether regulations change around security tokens and registration, bitcoin sits in its own sphere."
"I'd still be buying bitcoin," he said.
