American Bitcoin (ABTC), the Nasdaq traded Bitcoin treasury and mining company backed by Eric Trump and Donald Trump Jr., has brought its holdings to 4,004 BTC now worth about $415 million, the company announced on Friday. 

The firm said that between October 24 and November 5, ABTC had snapped up 139 Bitcoins now worth more than $14 million between October 24 and November 5. American Bitcoin is the 25th largest Bitcoin treasury, according to bitcointreasuries.net data. 

“We continue to expand our Bitcoin holdings rapidly and cost-effectively through a dual strategy that integrates scaled Bitcoin mining operations with disciplined at-market purchases,” American Bitcoin co-founder and Chief Strategy Officer Eric Trump said. 

American Bitcoin stock was trading nearly 2% higher Friday afternoon in New York. The firm, which went public in September, had dipped earlier in the day.

Bitcoin was recently trading at about $103,369, up 3% over the past 24 hours, amid an upturn in wider crypto markets. But the digital asset is off about 18% since reaching an all-time high above $126,000 in early October. 

American Bitcoin formed when the Trump brothers merged their own business entity earlier this year with Hut 8, a Canada-headquartered miner. The joint venture then went on to combine with Gryphon Digital Mining via a stock-for-stock merger. Gryphon was already publicly traded.

American Bitcoin is one of more than 200 publicly traded companies—many outside the crypto industry—following the approach of Nasdaq-listed Strategy, which has accumulated the world’s largest crypto treasury.

Strategy—formerly MicroStrategy—pivoted from software development to buying Bitcoin in August 2020 to generate better returns for its shareholders as its stock price floundered. It now holds more than 641,000 Bitcoin worth over $66 billion. 

In a Myriad prediction market, 95% of respondents do not expect Strategy to sell any of its BTC by the end of 2025. Myriad is a unit of Dastan, Decrypt’s parent company.

Firms in the Bitcoin mining industry are typically warehouses full of expensive, specialized computing equipment that process transactions and mint new digital coins for the biggest and oldest crypto network.

The sector has been hard-hit as Bitcoin’s price increase has slowed and as the challenges of mining have become more pronounced. Last year’s Bitcoin halving reduced the mining rewards for verifying blockchain transactions from 6.25 to 3.125 BTC. 

A number of miners have shifted to high-powered computing for the AI space in order to generate income as mining has become less lucrative.
