Bitcoin today: $73,761 low as $1 billion is liquidated, Nvidia opens a probe, Iran talks stall
Bitcoin dipped to $73,761 on Sunday night, its lowest since August, as more than $1 billion of leveraged positions were closed. Nvidia's board opened an investigation into its chief executive and Iran talks stalled. A bitcoin still costs about $19,533 to make on the best machine.
Bitcoin touched $73,761 on Sunday night and more than $1 billion of longs were closed
Bitcoin fell to about $73,761 late on Sunday 8 November, its lowest since August, before bouncing back above $75,000, according to CoinDesk. The same report counts more than $1 billion of leveraged positions closed in 24 hours on CoinGlass data, $913 million of it longs, with ether taking $448 million against bitcoin's $272 million. The bounce had already stalled when it was written.
Our own series puts bitcoin at $73,721 on the morning of 9 November, against $80,431 on 5 November. It shows $222 million of bitcoin longs force-closed on 8 November, on our liquidations chart, with another $37 million so far on 9 November. Twelve of the 193 days in that series were larger, led by $802 million on 2 June.
Nvidia's board opened an independent investigation into its chief executive
On Sunday Nvidia's board said it was opening an independent investigation after chief executive Jensen Huang was targeted by a foreign intelligence effort, NBC News reports. A committee of independent directors, helped by outside counsel, will oversee it. Nvidia said it has "no reason to believe that either national security or NVIDIA secrets were compromised".
Huang acknowledged an affair in a message to employees. NBC cites a person familiar with the matter saying US intelligence concluded the woman involved was a Chinese spy; China's foreign ministry called the allegation "unsubstantiated". CoinDesk links the weekend's thin-market volatility to the story. Nvidia closed Friday at $186.64, and CoinDesk notes the Nasdaq fell nearly 5% last week, extending a four-week losing streak.
Talks with Iran stalled, and oil has been moving bitcoin
Secretary of State Marco Rubio said Iran's demands were "outrageous" and that the talks had made no progress, CoinDesk reports. The same article observes that bitcoin has more often than not fallen during oil rallies since the Iran war began in March.
Spot ETFs lost $870 million over the four days we hold this week
On our ETF flows chart, the US spot bitcoin funds lost $399 million on 2 November, $116 million on 3 November and $430 million on 5 November, with a $75 million inflow on 4 November in between. That is a net outflow of $870 million across those four days. Our series has no figure for 6 November yet.
Difficulty is on course to fall 6% on the next reset
Blocks have been slow since the 29 October reset, and our estimate for the next one stands at −6.28% with 600 blocks to go, the first fall of more than 5% since July. We looked at what that does for a petahash in today's data piece: about 7% more coins. Hashprice in dollars is $31.44 per petahash a day on 9 November, from $36.19 on 29 October.
What it means for miners
A falling price is when an efficient machine on cheap power stacks the most coins for each dollar it spends, and the coins are the point. On 9 November the most efficient machine in stock, the S23 XP Hyd on Nigeria's 3.9 cents a kilowatt-hour, makes a bitcoin for about $19,533 in electricity, against a market price of $73,721. That is about a quarter of the price.
The fall in difficulty that is coming lowers that cost again, by the same 6%. Earnings are not guaranteed, and these figures hold today's conditions flat, but the electricity behind a coin does not depend on the day's liquidations.
