Casares brings his cryptocurrency experience to PayPal, which started allowing its merchants to accept bitcoin in 2015. Schulman, who officially took over the reins of a newly public PayPal in July 2015, has been open about his excitement for alternative currencies and new technologies in “fintech.”

At a Business Insider conference in December 2014, Schulman said he was particularly interested in the potential of blockchain technology, which is the distributed transaction processing engine behind cryptocurrencies such as bitcoin.
