Answer: Slippage is a common issue on decentralized exchanges (DEXs) due to their limited liquidity and order book depth. Slippage occurs when an order is filled at a price worse than the expected price, resulting in a higher transaction cost. On centralized exchanges (CEXs) like Binance, slippage is often not an issue due to their larger liquidity and order book depth. This allows traders to buy or sell assets at the expected price without worrying about slippage. However, it is important to note that slippage can still occur on large CEXs, especially during periods of high volatility or heavy trading volume.
