Bitcoin today: $3.6 billion leaves Binance as it reopens, bitcoin ETFs' worst day since June

Binance began paying out again on Sunday and $3.64 billion net left in under ten hours, 2.1% of its assets. Bitcoin funds took their largest one-day outflow since June on Friday, $643 million. Bitcoin held near $78,000, and a petahash earns the fewest coins since December.

Binance reopened withdrawals and $3.64 billion net left in under ten hours

Binance began restoring withdrawals in phases at 06:00 UTC on Sunday, three days after the $6.3 billion theft, with bitcoin and assets on 15 other blockchains first, CoinDesk reported. Services for all 15 were back by 12:36 UTC. Binance said further phases follow only after each blockchain clears security and stability checks.

Between 06:00 and 15:30 UTC it processed $4.65 billion of withdrawals against $1.01 billion of deposits, a net outflow of $3.64 billion, which it put at 2.1% of the $171 billion in its latest proof of reserves, according to CNBC. Cointelegraph cites DefiLlama data for $5.8 billion of net outflows over a 24-hour window, a different measure. Binance said withdrawals surged at first and then slowed and stabilised.

It also said it has now replaced about 95% of the stolen assets from company funds, up from 90% a day earlier. The rest is in less liquid tokens that take longer to buy. The FBI has attributed the theft to North Korea's TraderTraitor group; our report from the day of the theft has the first 24 hours.

Bitcoin funds lost $643 million on Friday, their biggest day out since June

US spot bitcoin ETFs had $643.2 million of net outflows on Friday 30 October, according to Farside Investors' figures as reported by crypto.news. BlackRock's IBIT lost $233.7 million and Fidelity's FBTC $201 million. It is the largest day since 25 June, when $691.7 million left, and ended a four-day run of inflows worth $440.8 million.

October closed with a net outflow of about $515.9 million, after September's inflows. Our ETF flows chart shows the same day. The funds held about 1.294 million bitcoin at the end of the week. The same report puts ether funds at a $1.61 billion net outflow for the month, so the selling was not confined to bitcoin.

Difficulty rose 5.54% on Thursday and a petahash now earns the fewest coins since December

The network's mining difficulty rose 5.54% to 148.36 trillion on Thursday 29 October, its second rise of 5% or more in two weeks, per mempool.space's retarget list. Bitcoin closed at $77,802 on Friday, down from $81,275 on Thursday, and at $78,095 on Monday.

A petahash earned 0.000426 bitcoin a day on 1 November, the lowest since 10 December 2025, and the best machine we stock now makes a coin for about $19,600 of electricity against a market price near $78,100. Our full piece on the cost of a coin has the month's numbers.

What it means for miners

The week's headlines were about coins held on exchanges and in funds. A miner who keeps the coins in their own wallet had no exchange to wait for on Sunday and no fund to redeem from on Friday. What does move a miner's results is the network: difficulty up 11.8% in October and a Fear & Greed reading of 37 on Monday, up from 30 on Saturday.

A coin costs about a quarter of its price to make on the most efficient machine on cheap power: it sells for 3.99 times the electricity behind it. Output is not guaranteed and moves with difficulty and price every fortnight; the next retarget, about ten days away, is estimated at -1.7% on our difficulty adjustments chart.
