Why slippage happens

Slippage is the difference between the price you expected when you placed a trade and the price you actually got. Prices can move in the moment between placing an order and it being filled, and in a thin market a large order can use up the best prices on offer and fill the rest at worse ones.

Ways to limit it

A limit order only fills at your price or better, though it may not fill at all. Many crypto apps also let you set a slippage tolerance, which cancels the trade if the price moves more than you allow. Splitting a large order into smaller ones can help too.
