Economic sanctions, as well as frauds and scams, tend to drive illicit crypto activity in the countries where it's most prevalent.

The companies whose transactions create bitcoin do well when the currency is up, but need more energy to keep going.

Crypto companies have spent more than $119 million so far, almost half of corporate money given during elections this year.

People have attributed symptoms from ringing ears to heart issues to the noise, Andrew Chow of Time explains.

The official Republican platform adopted earlier this week says the party will "defend the right to mine bitcoin."

The Federal Election Commission says crypto donations are subject to the same rules and contribution limits as conventional contributions are — but some states ban them, as the currencies are harder to trace and regulate.

It could soon be easier to buy and sell ether, a cousin of bitcoin, via traditional market mechanisms.

Bitcoin halving happens approximately every four years, and it's a big deal for the philosophical premise of the cryptocurrency.

The cryptocurrency's price is up about 40 percent this year, inching closer to its pandemic-era high of nearly $69,000 per coin, and vindicating those who held on through recent lows.

The 2-year moratorium prevents the repurposing of fossil-fuel burning power plants into crypto mining operations.
