What does slippage mean in cryptocurrency?
Slippage in cryptocurrency is the difference between the expected price of a crypto trade and the price at which it is actually executed.
For example, you place an order to buy Bitcoin at $78,000, but the trade is executed at $80,000. The difference is slippage. In this case, it amounts to about 2.5% — not critical, but noticeable.
Sometimes the situation can be the opposite: the trade is executed at a more favorable price. This is called positive slippage. For example, you:
- planned to buy at $78,000 but bought at $77,500 (a gain of $500);
- wanted to sell at $78,000 but sold at $78,500 (also a gain of $500).
However, such cases occur much less frequently.
Why does slippage occur in cryptocurrency?
The main reasons are related to market characteristics:
1. Low liquidity
Liquidity shows how easily an asset can be bought or sold at the current market price. If there are few buyers and sellers in a trading pair, there may simply not be enough volume available at the selected price.
For example, a trader wants to buy cryptocurrency at $100, but only a small portion of the required volume is available at that price. The remaining part of the order will be executed at $101, $102, or higher. As a result, the average purchase price will be worse than expected.
This situation most often occurs with little-known tokens (digital assets on a blockchain) and on smaller exchanges.
2. Large orders
The larger the trade amount, the higher the likelihood of slippage. A large order can quickly absorb all available orders at the closest price levels.
For example, if a trader buys a small amount of BTC, the trade has almost no impact on the market. But if they place a large order, there may not be enough sellers at the current price. Then the exchange starts executing the trade at the next, less favorable prices.
That’s why large trades are often split into several parts.
3. Wide spread (difference between bid and ask prices)
The spread is the difference between the lowest selling price and the highest buying price.
For example, buyers are willing to pay $98 for a token (a digital asset on a blockchain), while sellers are only willing to sell at $102. The $4 difference is the spread.
The larger this gap, the harder it is to execute a trade at the expected price. A wide spread usually indicates low activity in the trading pair. If a trader places a market order, the trade may be executed immediately at a less favorable price.
4. High volatility
Volatility refers to sharp and frequent price changes of an asset. In the crypto market, prices can change significantly within seconds.
For example, a trader sees a price of $78,000 and places a buy order for Bitcoin. But while the order is being processed, the price may already rise to $78,300 or $78,500. As a result, the trade is executed at a higher price than expected.
This happens especially often during major news events, sharp market drops, or strong rallies.
5. Network congestion
This reason is especially relevant for decentralized exchanges. On such platforms, trades are recorded on the blockchain, meaning transactions must be confirmed by the network.
If the network is congested, confirmation may take longer. While the transaction is being processed, the token price (a digital asset on a blockchain) in the liquidity pool may change. As a result, the user sees one rate when creating the trade, but the swap is executed at a different rate.
This often happens during periods of high activity, when many users are simultaneously making transactions.
How to reduce slippage
It’s difficult to avoid it completely, but the risks can be significantly reduced.
Use limit orders
A limit order allows you to specify in advance the price at which you are willing to buy or sell cryptocurrency.
For example, if you want to buy Bitcoin only at $78,000, you place a limit order at that exact price. The trade will only be executed if the market reaches that level. If the price is not met, the order will remain open or be partially filled.
This helps avoid situations where a trade is executed at a higher price than expected.
Set slippage tolerance
On decentralized exchanges, you can usually manually set the maximum slippage percentage.
For example, if you set a slippage tolerance of 1%, the trade will only be executed if the price changes by no more than 1%. If the deviation is greater, the transaction will be canceled.
Such a limit protects against significant price deterioration, especially when swapping low-liquidity tokens (digital assets on a blockchain).
Choose liquid assets
The more popular a cryptocurrency and the higher its trading volume, the easier it is to buy or sell it at the expected price.
For example, Bitcoin and Ethereum usually have many buyers and sellers, so the risk of significant slippage is lower. Lesser-known cryptocurrencies often have weak liquidity, so even a small trade can noticeably affect the price.
Before trading, it’s worth checking the trading volume and liquidity of the selected pair.
Split large trades
To reduce risk, it’s better to divide a large purchase or sale into several smaller operations. This way, the trade has less impact on the market, and the average execution price may be more favorable.
This method is especially useful when trading low-liquidity cryptocurrencies.
Monitor the spread
Before placing an order, it’s important to assess how much the current price differs from nearby orders. If the bid-ask spread exceeds 2%, the risk of slippage increases significantly.
Extra caution is needed when dealing with lesser-known cryptocurrencies and pairs with low trading volume. In such cases, even a small order may be executed at a worse price.
If the price gap is too large, it’s better to reduce the trade size, wait for a more active market, or choose another trading pair.
Use alternative platforms
Sometimes it’s more выгодно to execute a trade not on a single exchange, but to compare conditions across different platforms. One exchange may have low liquidity and a high spread, while another may offer a better rate and more orders.
You can also use exchange services with fixed rates. In this case, the transaction price is known in advance, and the risk of slippage is usually lower. The main thing is to ensure the service has sufficient reserves to complete the transaction.
