Bitcoin sat near $74,800 on Tuesday morning as the listed miner MARA disclosed it had sold 13,597 bitcoin since September. US October inflation is due at 13:30 UTC. A bitcoin still costs about $19,489 to make on the best machine.

MARA disclosed it sold 13,597 bitcoin, 40% of its holdings, since September

MARA Holdings said in its third-quarter shareholder letter on Monday that it sold 13,597 bitcoin for about $1.1 billion after the end of September, according to CoinDesk. That is 40% of the 34,012 it held on 30 September and six times the 2,247 it mined in the quarter. It used $750 million to repay loans secured on its coins and says it intends to keep using bitcoin to build cash for AI infrastructure.

We read the letter itself and wrote it up in full: MARA sold 13,597 bitcoin, 40% of its holdings, after mining 2,247 in the quarter. The short version for a miner is that the company chose to sell, and a coin cost it $39,674 in energy by its own figure.

Crypto fell with tech on Monday and traders bought protection

Only five of the top 100 cryptocurrencies were up 1% or more in the 24 hours to Monday morning, CoinDesk reports, as a selloff in technology shares weighed on the market. Bitcoin was at $74,580. Crypto futures liquidations came to about $1.1 billion across the market, $305 million of it bitcoin's.

Options show the mood. One-week implied volatility on bitcoin rose to about 43% from about 33% on Thursday, the premium for puts over calls rose to about 13% from about 2%, and four of the six most active bitcoin options were puts at $70,000 to $72,000 strikes, according to the same report. Ether closed Sunday below its 200-day average for the first time since 18 August.

Our own series has bitcoin at $74,707 on 9 November and $74,784 on 10 November, with $41 million of longs and $28 million of shorts force-closed on the 9th on our liquidations chart, small beside the $222 million of longs on Sunday 8 November.

US October inflation is due at 13:30 UTC

The US consumer price index for October is released at 8:30 a.m. New York time, 13:30 UTC. CoinDesk puts the Dow Jones consensus at +0.3% for headline inflation and +0.2% for core on the month, after +0.6% and +0.3% in September (CoinDesk). The same report notes bitcoin peaked above $87,000 in early October and has drifted lower since.

Producer prices follow on 13 November, the Fed's October meeting minutes on 18 November and the PCE report on 25 November. Analysts quoted in the piece disagree on whether a soft reading would be enough: BRN says bitcoin "needs real buying, not a lucky break".

Bitdeer reports before the US open, after MARA and HIVE on Monday

CoinDesk's week-ahead calendar lists MARA and HIVE Digital Technologies reporting after Monday's close and Bitdeer Technologies before the open on Tuesday.

Difficulty is on course to fall 6.6% at the next reset

On 10 November our estimate for the next difficulty reset is −6.58%, with 470 blocks to go. Blocks found per day fell to 111 on 8 and 9 November, the fewest since 3 June. We looked at what the cut hands back to each petahash in Monday's data piece, and at why the network's pay fell 23% in a fortnight while a petahash lost only about 5% in today's. Hashprice is $31.97 per petahash a day on 10 November.

What it means for miners

A bitcoin costs about $19,489 to make on the most efficient machine in stock, the S23 XP Hyd, at Nigeria's 3.9 cents a kilowatt-hour, against a market price of $74,784. That is about a quarter of the price, in electricity.

A falling price is when an efficient machine on cheap power stacks the most coins for each dollar spent, and a cut in difficulty lowers the cost of a coin again by the same share. Earnings are not guaranteed, and these figures hold today's conditions flat.
