Bitcoin traded at $81,990.4 as of 12:08 WIB on Tuesday, October 20, 2026, down 0.76% over the past 24 hours, according to Binance USDT-M Futures data compiled by Queenby News. BTCUSDT volume came in at $10.44 billion. While most major assets slipped, BRUSDT spiked 36.95% on $491 million in volume, making it the day's most extreme mover in futures markets.

Ether also weakened, down 0.70% to $2,407.9 on $6.80 billion in volume. Solana edged down 0.41% to $105.01 with $1.26 billion traded. BNB was the outlier among the top five assets by market cap, gaining 0.45% to $731.80. XRP slipped 0.51% to $1.3044 on $490 million in volume.

The day's wildest movers

Beyond the top five assets, the sharpest swings happened in smaller-cap tokens. Here's the list of biggest movers with at least $50 million in volume.

Top gainers:

• BRUSDT +36.95% ($491M volume)
• PHAUSDT +28.98% ($125M volume)
• CTRUSDT +16.37% ($56M volume)
• GTCUSDT +11.63% ($243M volume)
• AGTUSDT +10.20% ($340M volume)

Top losers:

• BTWUSDT -24.54% ($250M volume)
• QUSDT -23.05% ($803M volume)
• SIRENUSDT -14.03% ($60M volume)
• SANDUSDT -8.10% ($74M volume)
• STRKUSDT -6.02% ($84M volume)

QUSDT stands out because it posted $803 million in volume despite a price crash of more than 23%, pointing to heavy trading activity amid a sharp sell-off.

Funding rates: who's paying whom

Funding rate is the periodic fee exchanged between long and short traders in perpetual futures contracts, settled every 8 hours. Exchanges use this mechanism to keep futures prices close to spot. A positive funding rate means longs are paying more, usually a sign long positions are crowded and getting expensive to hold.

Today's most positive funding rates were on SIRENUSDT (0.1653%), AGTUSDT (0.0436%), and APRUSDT (0.0111%). Interestingly, SIRENUSDT also appears among the biggest losers, down 14.03% in 24 hours. Falling price paired with still-positive funding suggests longs remain dominant even after the correction, a setup that can fuel further unwinding if the price keeps sliding.

On the other side, the most negative funding rates were recorded on BTWUSDT (-0.3303%), CTUSDT (-0.2715%), and SANDUSDT (-0.1884%). Negative funding signals shorts are more numerous or more aggressive, so short traders end up paying longs. BTWUSDT itself has already plunged 24.54% in 24 hours, so the extreme negative funding lines up with the ongoing selling pressure.

Open interest and long/short ratios on BTC and ETH

Open interest is the total value of futures contracts still open and not yet closed out. It's a gauge of how much money remains actively positioned in a given futures market.

BTCUSDT open interest sits at $7.78 billion, up 1.8% over the past 7 days. By account count, 63% of BTC futures accounts are long, with a long-to-short ratio of 1.69 to 1. In other words, by number of accounts, long traders significantly outnumber shorts even as BTC's price weakened over the past day.

For ETH, open interest stands at $5.50 billion, down 1.3% over the week. The long bias among ETH futures traders is even more pronounced, with 75% of accounts long and a ratio of 2.97 to 1. A falling open interest paired with such a high share of long accounts suggests some traders are trimming exposure even as the majority who remain still favor the long side.

Taker buy/sell: who's more aggressive

Taker buy/sell ratio measures the volume of trades executed aggressively by buyers versus sellers. A ratio above 1 means buyers are hitting market orders more than sellers, signaling stronger buying pressure during that window.

For BTCUSDT, yesterday's taker buy/sell ratio came in at 1.05, tilted slightly toward buyers. ETHUSDT sat at a similar level, 1.04. Both numbers show buying activity was marginally more aggressive than selling over the past 24 hours, even though both assets closed lower in the same period. This mismatch between a buy-leaning taker ratio and falling prices often happens when selling pressure comes from large limit orders or liquidations rather than aggressive taker selling.

What it means for traders

A few concrete things worth watching from today's data:

• SIRENUSDT's funding staying positive (0.1653%) despite a 14.03% price drop deserves attention. If the price keeps falling while funding hasn't turned negative, there's a risk long positions remain overcrowded and could trigger further liquidations.
• BTC's 63% long ratio and ETH's 75% long ratio show retail futures accounts leaning bullish even as both assets weakened in the past 24 hours. A heavy long skew during a price decline is the kind of setup traders often watch for long squeeze risk.
• BTC open interest rising 1.8% over 7 days while price holds near $81,990 could mean fresh positions are building on both sides. Whether this resolves with a breakout above nearby resistance or more volatility through liquidations is worth tracking.
• BTWUSDT's extreme negative funding (-0.3303%) amid a 24.54% price drop shows shorts still dominate. If there's a sudden price reversal, this swollen short position carries squeeze risk.
• The heavy $803 million volume on QUSDT during its 23.05% crash is worth monitoring as a sign that liquidations or large position unwinding may still be underway.

What is a funding rate in crypto futures?

Funding rate is a periodic payment exchanged between long and short traders in perpetual futures contracts, typically every 8 hours. A positive rate means longs pay shorts, while a negative rate means shorts pay longs.

Why did BTC price drop while open interest rose?

BTCUSDT open interest climbed 1.8% over 7 days even as price fell 0.76% in 24 hours. This can mean new positions were opened on both sides, with the market yet to settle on a clear direction.

What's the difference between long/short account ratio and taker buy/sell ratio?

The long/short account ratio counts the percentage of accounts holding long versus short positions, regardless of position size. The taker buy/sell ratio measures aggressive buy volume versus sell volume over a given period.
