But such teams exist in the real world and can be hired to test the tightest security.

And in Granbury, Texas, a 24ft-high sound barrier was erected in 2023 at a mining site after residents complained to public officials that the nonstop roar was keeping them awake and giving them migraines.All these Bitcoin operations opened before Trump's return to the White House. But the opposition they have generated suggests public officials in Republican-voting areas are likely to find themselves coming under continued pressure from local people who oppose further Bitcoin mining expansion.

If this happens, could Trump's crypto dreams be derailed in his own backyard?Less than four years ago, Trump said Bitcoin "just seems like a scam". Yet those reservations have now gone: the Trump family has since started the crypto firm World Liberty Financial, and Trump launched his own cryptocurrency, $TRUMP – 220 of its top buyers were invited to a private gala dinner with the president on Thursday.Trump's sons Eric and Donald Jr are behind a crypto mining venture called American Bitcoin, which plans to trade on the Nasdaq stock exchange, and aims to build one of the world's largest and most efficient Bitcoin mining platforms, rooted in American soil.

Bitcoin mining has boomed in the US partly because of a crackdown in China in 2021, which was due to concerns over its environmental damage. Alexander Neumueller, an expert at the University of Cambridge's Centre for Alternative Finance, says that although it's hard to trace every last mine, it's clear that the US is now the leading Bitcoin producer, mining about 40% of the world's supply.Dresden is in New York's Finger Lakes region – a rural area sliced through with deep glacial lakes, which attracts tourists drawn by its wineries, breweries and outdoor pursuits. In Yates County, home to Dresden and the Greenidge plant, around 60% of voters picked Trump last November.

According to the owners of the mine, Greenidge Generation, anywhere from 40 to 120 Bitcoin a month are being produced at the plant, along with some energy that flows back to the grid.

The company – which turned down requests for an interview – has argued that they converted a coal-burning operation into a relatively cleaner gas-fired power installation that complies with state environmental laws."I don't think it would have mattered," he says. "We left at a time when we had a good candidate, she was fully funded.

"What we had set out to do, no-one thought we could do," he continues. "And we had become so successful in our agenda, it was hard to say, 'No, I'm going to stop now'... It was a hard decision."One he regrets? Surely withdrawing earlier could have given someone else a greater chance?

"No, I think it was the right decision." He pauses. "I think that… Well, it was just a difficult decision."Biden says he went into politics to fight injustice and to this day has lost none of his appetite for the fight. Last year at the D-Day celebrations he warned: "We're living in a time when democracy is more at risk across the world than at any point since the end of World War Two."
