## Desk highlights

The notes the desk scored highest this day, in full.

### 07:40 UTC · Coinbase discount on Bitcoin reaches 43 days

Bitcoin has traded cheaper on Coinbase than on the rest of the market for 43 days in a row. The gap reads -0.138% today, against a 7 day average of -0.127%.
The premium is the price difference between Coinbase's Bitcoin market and the global price. Today's gap sits a touch deeper than the past week's average, and every day of that week stayed on the discount side.
The figure records a price gap between venues, not the direction of the market, so a discount on its own does not tell you where $BTC trades next.

### 08:10 UTC · Put buyers outspent call buyers on Bitcoin

Bitcoin options buyers leaned toward protection over the last 24 hours. Takers spent $760.1K on puts, which pay off if price falls, against $443.5K on calls.
The largest single trades of the past 48 hours were all call sales, each negotiated as a block. Sellers collected $571.7K and $476.8K for $90,000 calls expiring Nov 27, and $343.8K for $75,000 calls expiring Oct 30.
Across 9,236 recorded trades, 23% of premium dollars changed hands as blocks, arranged off the order book and reported to the venue.

### 07:20 UTC · US buyers stay below global price 43 days

Coinbase priced Bitcoin below the rest of the world for a 43rd day in a row on Oct 17. US buyers closed the day paying -0.138% under the global price, the gap traders call the Coinbase premium.
That discount ran a little deeper than the past week's average of -0.127%. The size is small. What stands out is the length, with no day back on the paying side since the streak began.
In futures, quarterly $BTC contracts traded at an annualized +5.40% over spot, the extra cost of holding Bitcoin exposure through a dated contract instead of the coin itself.

### 05:40 UTC · Miners pulled back hashrate over the week

Miners ran less machinery on Bitcoin in the week to Oct 17. Our node counted 962 EH/s of hashrate, the total computing power securing the network, a -5.8% change against 7 days earlier. Measured over 30 days, it is still +8.1%.
Mining difficulty, the setting for how hard each block is to find, was 140.58T. Block space cost 2.0 sat/vB, the fee per unit of transaction data, and miners took in 462.0 BTC in revenue on the day.

### 03:10 UTC · Stock perp liquidations jump 68% in a day

Forced closures on Binance's TradFi perpetuals reached $85.08M on Oct 17, up 68% from $50.65M the day before.
Leveraged longs made up 74% of the total, $63.1M against $22.0M for shorts, spread over 218 contracts and 13,519 separate closures.
SOXL led with $12.20M, $8.25M of it on the long side. SNDK followed at $10.62M, nearly all longs at $10.31M. The single largest closure, $7.27M, hit SOXS, where $9.08M of short positions were closed in all. Crude oil ($CL) saw $5.52M of shorts closed out.

### 01:10 UTC · Ether longs took the day's heaviest losses

Traders betting on higher Ether prices took the hardest hit on Oct 17. Our streams recorded $42.7M of leveraged $ETH longs forced out, against $5.0M on the short side, the largest total of any coin.
Across 11 venues and 910 symbols, $249.1M was closed out in 80,555 events. Longs carried $192.2M of it, or 77.2%, with $56.8M from shorts. $BTC came next at $18.6M, and the single largest closure was a SOXS position on Binance.
The day ran 2% above the $244.2M of Oct 16 and stayed under the 7 day average of $312.8M. These totals are a floor drawn from the venues' public streams.

### 06:20 UTC · OKX lends dollars cheapest at 3.5%

OKX charged the least of the three venues we track to borrow dollars on margin in the 05:25 UTC read on Oct 18, at 3.5% a year for USDT. Binance charged the most at 4.71%, and Bybit's 3.92% matched the median.
Dogecoin showed the widest gap across 15 assets. On OKX, traders long $DOGE perpetuals paid 10.95% a year in funding, a fee that goes to the short side. Borrowing DOGE on the same venue cost 1% a year.
That left a recorded 9.95% spread between the two rates, the largest on the board in this read.

### 00:35 UTC · A $1.9M leveraged long forced out on Binance

Bitcoin spent the 24 hours to Oct 18 going almost nowhere, and a leveraged buyer on Binance still got forced out. The biggest closure of the window was a long liquidation of $1.9M on Binance, which is the size of the position closed, not the trader's loss.
$BTC ended the window -0.20% at $81,413. Our collectors caught 715 recorded prints of $1K or more across the day.
The heatmap behind the candles is an estimate of where leveraged positions sit. The prints on the candles are closures we recorded.
