We know some bitcoin investors are passionate about the cryptocurrency. But we’ve seldom seen that fervor from investment pros — until now.

On CNBC’s “Fast Money” Wednesday, pro-crypto panelist Dan Nathan, co-founder and editor of RiskReversal.com, and guest Rich Ross of Evercore ISI, who sees cryptocurrencies as shady, got into a lather over their digital divide.

Nathan called Ross “glib,” and Ross fired back at Nathan’s bearishness over the last two years, calling him “wrong on the market” and “not helping people make money.”

A visibly angry Nathan ranted, “You don’t know what I’ve done, you don’t know what my call is, so go piss off, seriously.”

Host Melissa Lee could only say, “Let’s go to commercial.”
