Short Selling

Short selling is a trading strategy where an investor profits from a decline in an asset's price. The trader borrows an asset, such as a cryptocurrency, and sells it on the open market with the intention of buying it back later at a lower price.

Once the asset is repurchased, it is returned to the lender, and the trader keeps the difference as profit. In derivatives markets, this is often executed through futures contracts or margin trading accounts.

Short selling provides liquidity to the market and facilitates price discovery by allowing participants to express negative views. However, it carries significant risk, particularly the potential for unlimited losses if the asset price rises unexpectedly.

This scenario can trigger a short squeeze, where short sellers are forced to buy back assets to cover their positions, driving prices higher.
