Incoming President Donald Trump has a new crypto and AI "czar": ex-PayPal COO David Sacks. "[Sacks] will work on a legal framework so the Crypto [sic] industry has the clarity it has been asking for, and can thrive in the US,” he wrote. In an interview with CNBC in 2017, Sacks said he believed that cryptocurrencies like Bitcoin and Ethereum fulfill the "original vision" of PayPal: creating a "database of money" in which payments never leave the system.
