Stocks of crypto-focused companies had a volatile Thursday as Bitcoin traded above $100,000 and then declined.

MicroStrategy (MSTR), a business intelligence service provider and the largest corporate holder of Bitcoin, saw its shares rise as much as 10% intraday but closed down around 4%. Crypto exchange Coinbase (COIN) rose before ending the day down 3%.

Other stocks that rose early and closed lower included Bitcoin mining companies Riot Platforms (RIOT) and Mara Holdings (MARA). Both ended the day down more than 4%.

Wednesday’s news that President-elect Donald Trump named Paul Atkins to head the Securities and Exchange Commission helped fuel the latest round of gains for Bitcoin and other crypto assets.

Atkins, an SEC commissioner under former President George W. Bush, has recently been working on issues related to digital assets. Atkins would replace crypto critic Gary Gensler, who announced he would step down in January.

The promise of a more crypto-friendly government has pushed Bitcoin prices up more than 50% since the day before Trump’s election victory. Bitcoin recently traded closer to $95,000 after previously breaking above $103,000.
