What is Leverage?
Crypto Glossary Definition
Using borrowed money to increase the potential gains or losses of an investment.
Why Leverage Matters
Leverage is the multiplier applied to a margin position — 10x leverage means a 10% adverse price move can wipe out the entire position. Higher leverage dramatically lowers the price move needed to trigger a liquidation, which is why it's considered high-risk even by experienced traders.
Leverage in Practice
Picture a trader named Alicia who opens a position on a perpetual futures exchange using 10x leverage, putting up $1,000 of her own collateral to control a position worth $10,000 in Bitcoin exposure. If Bitcoin's price rises by 5%, her position gains $500, a 50% return on her original $1,000, since the leverage multiplies both gains and losses relative to the underlying price movement. But if Bitcoin instead drops by just 10%, the loss on her $10,000 position wipes out her entire $1,000 of collateral, and the exchange automatically liquidates her position, closing it out before losses can exceed what she put up, since the exchange itself, not Alicia, would be on the hook for any deficit beyond her collateral. Chastened by the experience, she later tries a much more conservative 2x leverage on a similar trade, meaning Bitcoin would now need to fall roughly 50% before triggering the same kind of forced liquidation, giving her far more room to be wrong without losing everything. This illustrates why experienced traders treat leverage level as one of the most important risk decisions they make on any single trade, since higher leverage doesn't just amplify profit potential, it proportionally shrinks the price move needed to erase an entire position.
