As you might have suspected this Cyber Monday morning, the big stories on Engadget involve good deals or even an all-time low price on gadgets, accessories for said gadgets or services to run on them.

That said, according to early figures, it might have been a more muted Black Friday online than in previous years. Adobe estimates its combined Black Friday and Thanksgiving Day internet sales were less than last year, for the first time ever — even if it was only a mere dip from $9 billion in 2020 to $8.9 billion last week.

Adobe thinks the dip reflected the multitude of internet deals out there that began ahead of Black Friday — some as early as October.

Cryptocurrency mining in Kazakhstan is leading to power shortages

China's crypto mining ban may be partly to blame.

The Morning After

The Financial Times reports the country's electrical grid operator KEGOC said it would start rationing electricity for 50 registered miners after their demand reportedly invoked an emergency shutdown mode at three power plants in October. They'll also be the first users disconnected if there are grid failures. The energy ministry estimated electricity demand has jumped by eight percent so far in 2021 versus the more typical one or two percent. There have been blackouts in six regions since October.
