The bitcoin halving is set to take place in the next few days, which will cut miners' main stream of revenue in half. "We believe a bitcoin price above $60,000-$65,000 means the halving is de-risked for nearly all public miners," Needham analyst John Todaro wrote in a note to clients on Tuesday. It currently costs miners between $36,000 and $52,700 to mine a single bitcoin, Todaro said. Miners offer amplified exposure to bitcoin's price action, which has been more volatile since the launch of bitcoin ETFs introduced more leverage to the market. "That's propelled bitcoin to a threshold where the miners are really generating healthy economics," said Colonnese.

Of that, at least $9.1 million came from a crypto wallet that U.S. blockchain analysis firm TRM Labs said was linked to pig-butchering scams. Neither did the Thai government, the Thai police or the Bangkok-based trade group Wang represented, the Thai-Asia Economic Exchange Trade Association. The crypto account registered to Wang was held at Binance, the world’s largest crypto exchange, according to three blockchain analysis firms. In April, the U.S. Department of Justice said it seized about $112 million worth of crypto linked to pig-butchering scams, without identifying suspects. The crypto account in Wang’s name was registered in November 2020, according to the financial records Reuters reviewed.

☆ U.S. tackles loopholes in curbs on AI chip exports to China

The latest crackdown on tech exports to China coincides with U.S. efforts to thaw difficult relations between the world's two largest economies. One, named the H800, has as much computing power at some settings used in AI work as the company's more powerful but blocked H100 chip. The U.S. now plans to introduce new guidelines for AI chips that will restrict certain advanced datacenter AI chips that are not currently captured, the U.S. official said. In order to keep AI chips the U.S. views as too powerful from China, the official said the U.S. planned to remove one of the parameters — the "bandwidth parameter" — it has used to restrict exports of certain AI data center chips. This would likely mean the speed at which AI chips talk to each other would be reduced.

☆ Bitcoin miners beef up Texas operations ahead of extinction-level event, exclusive data shows

Bitcoin miners are barreling toward the "halving" — a major market-making event that some fear will be a death knell to many in the industry. "We're taking a long-term bet on bitcoin and on the fact that bitcoin mining will survive and will bounce back even stronger." Texas has grown to dominate bitcoin mining partly because of support from local authorities and the operator of the Texas energy grid, ERCOT. Even during the bear market, Texas miners are building out, buying new sites and fresh fleets of hardware. The mining company was spun off from Chinese bitcoin mining giant Bitmain and went public via SPAC earlier this year.
