Hedging

Hedging means intentionally taking a second position that moves opposite to an existing holding, so a loss on one leg is offset, partly or fully, by a gain on the other. It does not eliminate risk outright; it trades away some potential upside in exchange for a more predictable outcome, which is why professional traders describe hedging as insurance rather than a profit strategy.

The most common tool is a short position on a perpetual futures contract: a holder of spot Bitcoin can open a short of roughly the same notional value, so a price drop that erodes the spot position's value is offset by gains on the short. Because perpetuals never expire, they charge a periodic funding rate between longs and shorts, which becomes an ongoing cost or benefit of running the hedge. Options offer a different shape of protection: buying a put option sets a floor price at which an asset can be sold, capping downside for the cost of a premium, without forcing the holder to give up the position itself. A "collar" pairs that put with a sold call to offset the premium, at the cost of capping upside too.

Miners, market makers, and corporate treasuries hedge routinely, since their businesses depend on predictable cash flow rather than directional bets. Simpler hedges exist as well, such as rotating part of a portfolio into stablecoins during uncertain periods. The main risks are cost, since premiums and funding payments can erode returns, and leverage: a hedge built with margin can itself be liquidated in a sharp move, leaving the original exposure unprotected right when it was needed most.
