The Tesla (TSLA) CEO is now saying that his company has not sold any bitcoin (XBT) after earlier appearing to suggest the opposite. His original Twitter exchange had led bitcoin to extend its losses.

The latest cryptocurrency drama began Sunday when a user named CryptoWhale tweeted: "Bitcoiners are going to slap themselves next quarter when they find out Tesla dumped the rest of their #bitcoin holdings."

"With the amount of hate @elonmusk is getting, I wouldn't blame him," the user added.

Musk responded simply about an hour later: "Indeed."

Within hours, bitcoin had fallen below $43,000, having lost more than 8% over the last day, according to cryptocurrency tracker Coinbase. It had already lost some ground earlier on Sunday, but accelerated losses after Musk's post.

Musk later posted a follow-up tweet, writing: "To clarify speculation, Tesla has not sold any bitcoin."

Value of the digital currency immediately jumped about 3.7% — from $42,566 to almost $44,138 — within about five minutes of Musk's tweet, according to Coinbase.

Tesla did not immediately respond to a request for comment about its holdings in the digital currency.

Musk's posts came just days after he caused another stir last week, while announcing that Tesla would reverse plans to accept bitcoin as payment for its cars.

He cited bitcoin's high environmental cost as reason for the move.

"We are concerned about rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel,"
Musk said in a note posted on Twitter last Wednesday. "Cryptocurrency is a good idea on many levels and we believe it has a promising future, but this cannot come at great cost to the environment."

The environmental cost of mining — or creating — digital currencies has been well-documented for years.

The news sent bitcoin down about 12% at the time. It came after months of Musk personally hyping bitcoin and other popular cryptocurrencies, such as dogecoin.

Just before that, the CEO had asked his followers in a Twitter poll if they would like "Tesla to accept Doge."

Tesla and Musk have appeared fairly bullish on bitcoin for at least a few months, with the company disclosing in February that it had invested $1.5 billion in bitcoin and floating the ability to buy its cars using the cryptocurrency. Musk tweeted in late March that people "can now buy a Tesla with Bitcoin."

The company did say in a regulatory filing last month, however, that it assesses each quarter whether "events or changes in circumstances ... indicate that it is more likely than not that our digital assets are impaired." It also disclosed at the time that it had sold 10% of its bitcoin stake, earning a $101 million profit.

Last week, Musk said that Tesla still plans to use bitcoin after the currency finds cleaner energy sources.

"Tesla will not be selling any bitcoin and we intend to use it for transactions as soon as mining transitions to more sustainable energy," he wrote. "We are also looking at other cryptocurrencies that use [less than] 1% of Bitcoin's energy/ transaction."

Musk's other ventures have gotten in the action, too. Last week, his space exploration company, SpaceX, claimed that it would take dogecoin as payment for an upcoming mission.
