Arbitrage involves buying an asset in one market where the price is lower and simultaneously selling it in another market where the price is higher. This can apply to various financial assets, including cryptocurrencies, stocks, and commodities. The effectiveness of arbitrage depends on the speed of execution, transaction costs, and market efficiency. In the cryptocurrency market, arbitrage opportunities often arise due to the fragmented nature of exchanges and variations in liquidity. Traders employ algorithms and automated trading systems to quickly capitalize on these opportunities before the price discrepancies close.
