U.S. President-elect Donald Trump announced a major appointment today: he appointed former PayPal Chief Operating Officer David Sacks as the "White House A.I. & Crypto Czar", responsible for formulating and leading U.S. policies in the fields of artificial intelligence and cryptocurrency.

Trump said David Sacks will "create a legal framework that meets the regulatory clarity the cryptocurrency industry has long needed and will enable this industry to flourish in the United States."

Who is David Sacks?

Speaking of David Sacks, he is no ordinary person. He is the founding COO of PayPal and one of the core members of the legendary Silicon Valley team "PayPal Mafia". He made great contributions to the success of PayPal, and then he founded the enterprise software platform Yammer, which was finally sold to Microsoft for $1.2 billion, a classic example of "selling well". Now, this big man with more than 20 years of experience in Silicon Valley innovation will work with the White House to guide the US AI and cryptocurrency policies.

One stone stirs up a thousand waves

Behind this appointment is actually Trump's careful layout for the future of the US technology sector. David Sacks will work with Paul Atkins, the new chairman of the US Securities and Exchange Commission (SEC), to promote friendly policies for the cryptocurrency industry.

Paul Atkins, also considered a supporter of cryptocurrencies, is expected to take over from Gary Gensler in January and lead the SEC toward a more open regulatory attitude.

With the appointment of these two key figures, the future cryptocurrency and artificial intelligence policies in the United States may usher in a new round of changes. This is not only good news for the cryptocurrency industry, but also a situation worth looking forward to for technology enthusiasts and investors.

The question now is, can David Sacks make a comeback like he did at PayPal and Yammer? If he can really lead the United States to the forefront of technology, this "crypto czar" is definitely a "powerful" position!
