About this tag

Derivatives are the contracts that sit on top of spot - perpetual swaps, dated futures, and options. They exist to let traders take exposure without holding the asset, and in crypto they often carry more size than the spot market underneath them. That inversion matters. When the contract market is larger and more leveraged than the thing it references, the derivative stops following price and starts setting it. Much of what looks like spot movement is the derivatives layer resolving its own positioning.

Each instrument carries a cost that reveals where leverage is crowded. Perpetuals have no expiry, so the funding rate keeps them anchored to spot - longs pay shorts when the contract trades rich, and persistently high funding is not conviction but a mechanical drag that eventually forces exits. Futures carry a basis, the spread that cash-and-carry desks harvest by holding spot and shorting the contract delta-neutral. Options carry premium, time decay, and a strike, which is why their open interest and put/call shifts map conviction more honestly than commentary does.

This tag collects notes on reading those mechanics directly. What funding rates signal when they go extreme and how the flush clears overextended longs. How basis compression marks institutions unwinding. Why short squeezes feed cascading liquidations. What options data - put/call ratios, open interest, max pain, dealer delta-hedging - shows about positioning before price confirms it. The shared thread is that derivatives express cost, and cost reveals where the crowd sits.

The framing is structural, not directional. Funding, basis, and options skew do not predict the next move - they describe the pressure already loaded into the book. Read these as field notes on how leveraged positioning builds, where it becomes uneconomical to hold, and how the unwind reaches back into spot once the carry stops paying.
