On a weekday afternoon, drive west out of Austin, past the half-built subdivisions and strip malls, and eventually the land flattens into something quieter and older. You begin to hear it before you see it somewhere close to Rockdale, a town of only 5,600 residents that was once well-known for its aluminum. a steady, low hum. Racks of computers that spend every second of the day guessing numbers are cooled by thousands of fans that rotate in unison. The current global Bitcoin market sounds like this. And it sounds like Texas for reasons that seemed almost coincidental four years ago.
When Beijing declared it had finished mining cryptocurrency in the spring of 2021, the migration got underway. In a matter of weeks, the nation that formerly held about 70% of the global bitcoin hashing capacity was pushing its miners out. The day following the announcement, Poolin CEO Kevin Pan flew out of China and told the BBC he would never return. Alejandro De La Torre, his coworker, claimed that upon arriving in Austin, he received an AR-15 as a welcome gift. That picture has a telling quality. A recently arrived Chinese bitcoin executive is told he might want to go hunt wild hogs from a helicopter. Even if you tried, you couldn’t write it.

In Texas, the miners discovered a unique combination that is typically found only on a spreadsheet. Electricity was inexpensive, sometimes ridiculously so. In West Texas, solar and wind farms are generating electricity more quickly than transmission lines can transport it eastward, and prices sometimes fall into negative territory. Because burning natural gas is less expensive than moving it, Permian oil and gas companies flare it off. All of that appears to a miner to be a waste of money.
For his part, Governor Greg Abbott seized the chance. “It’s taking place! In June 2021, he tweeted, “Texas will be the crypto leader,” with an all-caps zeal that makes other states’ regulators cringe. Blockchain was incorporated into the state’s commercial code. Profits from cryptocurrency companies were not taxed. Additionally, the grid operator, ERCOT, secretly signed demand-response contracts with the largest miners, which pay the facilities to shut down when the grid is under stress. It’s elegant on paper. In reality, it’s challenging.
Because the catch is, of course, the grid. Anyone who experienced Winter Storm Uri in 2021 is aware of what occurs when Texas’s remote electrical system is overworked. In late 2022, Senator Elizabeth Warren and a few House Democrats sent ERCOT a pointed letter questioning whether it was really a good idea to add gigawatts of additional mining load, particularly given the rising annual volatility of the climate. In essence, ERCOT shrugged in response. Pablo Vegas, the agency’s new CEO, stated that the agency wanted to work with any company that was willing to participate. The miners were part of that.
The repercussions have become more personal in Hood County, which is southwest of Fort Worth. In 2023, a MARA Holdings facility moved in, putting almost 60,000 computers in shipping containers that were less than a football field away from people’s homes. The sound is described by locals as a leafblower pressed against the pillow and a plane that never lands. For the peaceful country evenings, Danny Lakey and his spouse purchased a log home. They now hardly ever sit on their porch, they told the Texas Tribune. For the sole purpose of enacting a noise ordinance, the approximately 600-person community is voting in November to become the city of Mitchell Bend. Texas counties are not legally permitted to write on their own.
The contradiction that permeates everything is difficult to ignore. In Texas, bitcoin mining is being marketed as a libertarian victory as well as a public service—a flexible load that absorbs stranded renewable energy and stabilizes the grid. There is some truth to that. In order to treat electricity as a tradeable asset rather than a sunk cost, companies such as Luxor Technology are now constructing whole energy-trading desks around mining operations. However, some of it is the kind of narrative an industry presents about itself in order to keep the neighbors at bay.
It’s really unclear if Texas will still be the global hub for bitcoin in five years. With each cycle of halving, mining economics change. The same inexpensive megawatts are being contested by AI data centers. Additionally, the political climate surrounding energy-intensive industries may change more quickly than anticipated. But the hum persists for the time being. Outside of Rockdale, fans continue to spin, computers continue to speculate, and a small Texas town continues to wonder exactly what it agreed to.
