NYU finance professor on bitcoin: I don't see why people are so upbeat on it

Aswath Damodaran, NYU finance professor, joins 'Closing Bell' to discuss rising rates, SPACs, and bitcoin. "It's a pricing case study, not a valuation," Damodaran said. "Whether bitcoin is a currency or collectable, it cannot be valued. It can be priced. The question we can ask is $60,000 a fair price for bitcoin?"
