Crypto as investment vs currency

Here at Marketplace, we often report on a monthly economic indicator from the University of Michigan called the consumer sentiment index. It basically looks how people are feeling about the economy. Now, a team of academics at the University of Pennsylvania's Wharton School have used that index as a model to create something similar though much more niche: how people feel about cryptocurrency. It's called the Consumer Cryptocurrency Confidence Index, a monthly survey now in its third year. Marketplace’s Stephanie Hughes spoke with Wharton marketing professor Dave Reibstein, one of the creators of the index, about what he hopes to accomplish with it.
