Recently, I encountered slippage issues during trading and remembered that many beginners actually have no idea what this thing is.

Simply put, slippage is when the price you expect to buy at and the actual transaction price are different. It sounds harmless, but in real trading, it can directly affect your profits. For example, you plan to buy 5 XYZ tokens at $200 each, totaling $1,000. But when you hit "market buy," the price instantly rises, and you only get 4.5 tokens, with the average cost soaring to $220. That’s slippage at work.

Why does slippage happen? There are mainly two reasons. One is extreme market volatility, and the more common one is insufficient liquidity. Especially with certain small-cap coins or trading pairs with low volume, slippage can be particularly noticeable. I saw a case where a "whale" bought $8.65 million worth of WIF, but due to slippage issues, most of the orders were executed at outrageous high prices, resulting in a huge loss.

Want to avoid getting caught by slippage? My advice is to use limit orders instead of market orders. Limit orders let you control the execution price, although it might not fill, at least you won’t get cut badly by slippage. Also, pay attention to trading fees—sometimes, slippage plus high fees can make your costs much higher than expected.

So next time you trade, remember to check the market depth and liquidity first, choose the right trading method, and be smarter in avoiding the trap of slippage.
