A number of very large institutions are coming into bitcoin, it's just the tip of the iceberg, says Paxos CEO Charles Cascarilla

Charles Cascarilla, Paxos CEO and co-founder, says everyone should have a little bit of bitcoin in their portfolios. The bitcoin ecosystem has grown and it could 'become gold.' "There's going to be a lot of other very large institutions coming in 2021. This is just the tip of the iceberg here. There's a finite amount of supply, which makes bitcoin valuable," Cascarilla said. He joins 'Halftime' to discuss the outlook for the cryptocurrency.
