WASHINGTON >> The price of bitcoin surged to over $109,000 early Monday, just hours ahead of President-elect Donald Trump’s inauguration, as a pumped up cryptocurrency industry bets he’ll take action soon after returning to the White House.

Once a skeptic who said a few years ago that bitcoin “seems like a scam,” Trump has embraced digital currencies with a convert’s zeal. He’s launched a new cryptocurrency venture and vowed on the campaign trail to take steps early in his presidency to make the U.S. into the “crypto capital” of the world.

His promises including creating a U.S. crypto stockpile, enacting industry-friendly regulation and event appointing a crypto “czar” for his administration.

“You’re going to be very happy with me,” Trump told crypto-enthusiasts at a bitcoin conference last summer.

Bitcoin is the world’s most popular cryptocurrency and was created in 2009 as a kind of electronic cash uncontrolled by banks or governments. It and newer forms of cryptocurrencies have moved from the financial fringes to the mainstream in wild fits and starts.

The highly volatile nature of cryptocurrencies as well as their use by criminals, scammers and rogue nations has attracted plenty of critics, who say the digital currencies have limited utility and often are just Ponzi schemes.

But crypto has so far defied naysayers and survived multiple prolonged price drops in its short lifespan. Wealthy players in the crypto industry, which felt unfairly targeted by the Biden administration, spent heavily to help Trump win November’s election. Bitcoin has surged in price since Trump’s victory, topping $100,000 for the first time last month before briefly sliding down to about $90,000. On Friday, it rose about 5%. It jumped more than $9,000 early Monday, according to CoinDesk.

Two years ago, bitcoin was trading at about $20,000.

Trump’s picks for key cabinet and regulatory positions are stocked with crypto supporters, including his choice to lead the Treasury and Commerce departments and the head of the Securities and Exchange Commission.

Key industry players held a “Crypto Ball” on Friday to celebrate the first “crypto president.” The event was sold out, with tickets costing several thousand dollars.

As a candidate Trump promised that he would create a special advisory council to provide guidance on creating “clear” and “straightforward” regulations on crypto within the first 100 days of his presidency.

Details about the council and its membership are still unclear, but after winning November’s election, Trump named tech executive and venture capitalist David Sacks to be the administration’s crypto “czar.” Trump also announced in late December that former North Carolina congressional candidate Bo Hines will be the executive director of the “Presidential Council of Advisers for Digital Assets.”

At last year’s bitcoin conference, Trump told crypto supporters that new regulations “will be written by people who love your industry, not hate your industry.” Trump’s pick to lead the SEC, Paul Atkins, has been a strong advocate for cryptocurrencies.

Crypto investors and companies chafed as what they said was a hostile Biden administration that went overboard in unfair enforcement actions and accounting policies that have stifled innovation in the industry.
