Bitcoin Miners Drawing Power From Grids Will Face 'Reckoning' Post Next Halving, MARA Says

Bitcoin miners that are still drawing electricity from grid-attached power sources will struggle after the next halving event in 2028, MARA Holdings (MARA) said in a shareholder letter.
"For those miners still relying on grid-attached power, the writing is on the wall. Energy costs will only rise. The 2028 halving will likely force another industry-wide reckoning. Many may not survive," the letter said.
The statement comes as the mining industry has already been struggling to stay profitable following a recent halving event that saw bitcoin rewards cut in half, forcing some miners to diversify their revenue sources into high-performance computing (HPC) and artificial intelligence (AI).
