Bitcoin Liquidations by the Hour: Half of Six Weeks Landed in 56 Hours
Bitcoin liquidations do not arrive at a steady rate. Over 999 completed hourly readings to 2026-08-09, half of all the notional landed in 56 hours and the busiest 1% of hours carried 17.5%. Almost every hour is one way, while the whole panel pooled together looks balanced.

Bitcoin Funding Rates Only Beat the Last Settlement in the Final Three Hours
The funding rate a venue shows you before a settlement is a running average, not the rate it will charge. Over 496 Bitcoin perpetual venue-settlements to 2026-08-08, a read taken four hours out was no better than assuming the rate stays where it last settled. The screen only starts to separate inside three hours.

Bitcoin Perp Turnover Runs Three Times Faster on OKX Than on Hyperliquid
Turnover is the notional a venue traded in a day divided by the open interest still on its book. Run it on the same six Bitcoin perpetuals and the answers span a factor of seven, the two venues in the middle turn out not to be separable at all, and one venue's own open interest field doubles its own result.

Crypto Liquidation Data: Why the Reported Number Is a Floor, Not a Total
A crypto liquidation total is a measurement, not a fact, and at least one major venue documents that its public feed pushes only one order per symbol per second. Here is what the number counts, what it drops, and the four checks that make it usable.

Crypto Trading Hours: Which UTC Hours Move Bitcoin, and Which Are Noise

Crypto Drawdown Math: Why a 50% Loss Needs a 100% Gain to Break Even
Recovering a drawdown always costs more than the drawdown itself, and leverage widens the gap until liquidation ends it. Here is the recovery math, measured against Bitcoin's own live drawdown.

Crypto Bid-Ask Spread: Why the Tightest Quote Is Just the Smallest Tick
The quoted spread on a liquid crypto book is almost always exactly one tick wide, which makes a cross-venue spread ranking a tick-size ranking. Here is the live cross-venue evidence, and the two numbers to read instead.

Open Interest in Coins vs Dollars: Why the Same Crypto OI Can Rise and Fall at Once

How to Calculate Crypto Futures PnL: Entry, Exit, Funding, and Fees
