New York Governor Kathy Hochul has signed a two-year moratorium on bitcoin ( BTC-USD ) mining operations that are powered by carbon sources, otherwise known as Proof-of-Work crypto mining. The legislation makes New York the first state to partially ban PoW mining, a process that allows crypto miners to earn digital rewards by solving complex mathematical equations to authenticate transactions while using a hefty amount of computing power. The New York State Senate passed a PoW-targeted bill in June in an effort to address concerns about the high energy usage in bitcoin ( BTC-USD ) mining and thus its negative environmental impacts. Sustainable crypto miners (think of those that use Proof-of-Stake consensus mechanisms) likely cheered the eco-friendly legislation since more market share could open up for them.

Bitcoin ( BTC-USD ) miners, especially Core Scientific ( NASDAQ: CORZ ), Argo Blockchain ( NASDAQ: ARBK ) ( OTCQX:ARBKF ) and Iris Energy ( NASDAQ: IREN ), have been dealing with a tough mining environment as depressed BTC prices hurt revenue and a rise in energy prices increase costs, thus squeezing profitability. Miners: Riot Blockchain ( NASDAQ: RIOT ), Marathon Digital ( NASDAQ: MARA ), HIVE Blockchain Technologies ( NASDAQ: HIVE ), BIT Mining ( NYSE: BTCM ), Hut 8 Mining ( NASDAQ: HUT ), Bitfarms ( NASDAQ: BITF ), Bit Digital ( NASDAQ: BTBT ), CleanSpark ( NASDAQ: CLSK ), Greenidge Generation ( NASDAQ: GREE ) and Soluna Holdings ( NASDAQ: SLNH ). In July, Sen. Elizabeth Warren wanted crypto miners to disclose energy use, emissions .
