Short selling is a trading strategy where an investor bets that the price of an asset will decline. In the case of cryptocurrencies, this involves borrowing coins from a broker or an exchange and selling them at the current market price. The goal is to buy back the coins later at a lower price.When the price falls as anticipated, the investor repurchases the coins and returns them to the lender. The difference between the selling price and the repurchase price represents the profit. However, if the price rises instead, losses can occur, as the investor will have to buy back at a higher price.This strategy can be risky, particularly in the volatile cryptocurrency market. Prices can fluctuate dramatically in a short period, leading to potentially significant losses. Additionally, some platforms may impose margin calls, requiring traders to add more funds to their accounts if the market moves against them.In summary, short selling in cryptocurrency involves betting on price declines, with both profit potential and risk of loss.
