Bitcoin has been on a bit of a roller coaster ride the past few months. After climbing to over $16,000 in December, the price of bitcoin has tempered a bit at $8,950 as of this writing.

All of this talk about cryptocurrency and bitcoin in particular becoming a major currency isn’t new for Dorsey. In an interview with The Verge last August, he predicted that blockchain would become the “next big unlock” and noted that blockchain itself is not something with simply financial applications but that the ability to “distribute and decentralize the ledger enables proof of work, and proof of one entity, in an untrusted network.
