The cryptocurrency soared through the mark to a peak of $103,800, having enjoyed a blistering rally since the November 5 election of Trump, who pledged on the campaign trail to make the United States the "bitcoin and cryptocurrency capital of the world". The digital unit has jumped more than 50 percent since the tycoon's poll win -- and around 140 percent since the turn of the year. However, the unit's advance stalled in recent weeks, sitting just below $100,000 as traders awaited new catalysts to buy in.

That came with news that Trump has fingered major crypto proponent Paul Atkins to take over as chair of the Securities & Exchange Commission. Atkins, an SEC commissioner from 2002 to 2008, founded risk consultancy firm Patomak Global Partners in 2009, whose clients include companies in the banking, trading and cryptocurrency industries.

He would replace Gary Gensler, who led a crackdown on the sector after a 2022 market rout.

Even so, the SEC this year authorised the trading on the American market of two new financial products allowing a wider public to buy cryptocurrencies, called ETFs. One is backed by the price of bitcoin and the other by ether, the second most popular unit by capitalisation.

"Atkins, a conservative legal eagle with a track record of critiquing the SEC's tough stance on cryptocurrency firms, is expected to steer a more crypto-friendly course," said Stephen Innes at SPI Asset Management. "This strategic move has electrified the crypto community, fueling investor optimism about a potentially more accommodating regulatory landscape under Atkins' watch, aligning with broader Republican advocacy for a lenient approach to the flourishing digital asset market."

Despite having once branded cryptocurrencies a "scam", Trump changed his stance and has been a major advocate of the unit during his election campaign. In September, he announced that he, along with his sons and entrepreneurs, would launch a digital currency platform named World Liberty Financial. He has also become a close friend of tycoon Elon Musk, who he said would lead a new US government-efficiency group tasked with cutting federal waste. Musk reportedly spent more than $100 million to help Trump regain the White House, repeatedly boosting his candidacy on his X social media platform.

"Layer on top expectations he will strip back regulations on the crypto industry and you begin to understand why investors have piled into the digital currency and related stock," said Dan Coatsworth, an analyst at investment group AJ Bell.

Among the measures expected from the sector is the creation of a strategic reserve of bitcoins in the United States, consisting mainly of tokens seized by the courts, which could push other countries to grant more legitimacy to the virtual currency.
