Bitcoin was trading up a fifth from last week's lows on Monday

Bitcoin and ether will be at the heart of this reserve, he posted on Sunday.

US President Donald Trump said on Sunday that his January executive order on digital assets would create a stockpile of currencies including bitcoin, ether (ETH), XRP, solana (SOL) and cardano (ADA) in the US strategic reserve.

The names of the tokens were not previously announced by Trump.

Bitcoin and ether will be “at the heart” of this reserve, he posted on Truth Social.

The post had sent the world’s largest cryptocurrency up by more than 20 percent from the November lows it was trading at on Friday, flipping sentiment on a token that has been sliding since mid-January on disappointment Trump has not followed through on pledges to loosen regulation.

It was last trading around US$94,154, up from Friday’s US$78,273.

Ether has risen by a fifth over the weekend and was last at US$2,482, XRP was up 38 percent, solana 20 percent and cardano was last at US$2,182, a 78 percent gain.

Bitcoin-related ETFs listed in Hong Kong rallied, with ChinaAMC Bitcoin ETF (3042) and Bosera HashKey Bitcoin ETF (3008) jumping 17.7 percent, CSOP Bitcoin Futures ETF (3066) surging 17.6 percent, and Samsung Bitcoin Futures Active ETF (3135) climbing 17.3 percent.

Trump’s post detailing the inclusion of tokens in the reserve is “clearly a positive shock to the crypto scene and a shot in the arm for a market desperately in need of a catalyst to alter the bear trend lower”, said Chris Weston, head of research at Australian online broker Pepperstone.

It is possible the rally will extend into the first White House Crypto Summit Trump is hosting on Friday, with the risk that the bearishness in other markets could weigh on sentiment, he said.

While Wall Street closed higher on Friday, the recent selloff in large technology bellwethers such as Nvidia has eroded confidence in bitcoin, which some see as an alternative tech proxy.

Bitcoin fell more than 17 percent in February, clocking its biggest monthly percentage fall since June 2022 and losing more than a third of its price since topping US$105,000 in early January.

Its rally since Trump’s November election was spurred by optimism that the crypto-friendly president would champion a strategic bitcoin fund and end the previous Joe Biden administration’s crackdown on the industry.

But beyond a flurry of appointments of crypto-friendly officials when Trump took office, there has been little concrete news so far around that policy for investors.

“While this announcement has significantly boosted prices, it has also raised concerns,” wrote IG market analyst Tony Sycamore.

The funding for cryptocurrency purchases in the reserve could either come from US taxpayers or the cryptocurrencies in the asset will be those seized in law enforcement actions, he said.
