How to use a crypto exchange: fees, spread and order types
A quoted crypto price is only one part of a trade. Learn how exchange fees, bid-ask spread and order type affect the amount you receive.
A crypto exchange matches buyers and sellers or offers an instant conversion. The number at the top of a market page is a useful reference, but it may not be the price available for your size of order. Before placing a trade, find out which asset you will receive, which network you will use and what the platform charges.
Read the two sides of a price
The bid is what a buyer is willing to pay; the ask is what a seller requests. The gap is the spread. A displayed midpoint can sit between them, so multiplying it by your amount may overstate what you receive. An instant-swap quote may build its cost into the rate instead of showing a separate fee.
Market order or limit order?
A market order prioritizes execution against available offers. It can fill at several prices when liquidity is thin. A limit order states the worst price you accept, but it might never fill. Both may incur trading fees, and exchange rules vary. Read the order preview before confirming.
Costs to include in your comparison
- Trading fee: charged when an order executes.
- Spread and slippage: difference between a reference or expected price and the actual fill.
- Withdrawal fee: charged by a service when moving assets out.
- Network fee: paid for a blockchain transfer; it can change over time.
For a coin-to-coin trade, also check whether the venue uses a direct market or two trades through a common quote asset. Two legs can mean two sets of costs. A pair can have a price without enough depth for a large order.
Use a converter as a starting estimate
The Crypto Exchange converter derives an indicative cross rate from coin/USDT prices and caches the current batch for about one minute. It cannot see your account’s fee tier or guarantee a fill. For example, SOL to ZEC is a reference ratio, while a trading screen shows executable choices. Always compare the final quantity on that screen with the estimate before you accept.
When comparing two venues, enter the same starting amount and record the final quantity after all visible fees. A lower advertised trading fee can still lead to a worse result if its spread is wider. Keep the destination network in the comparison: a cheap trade followed by an expensive or unsupported withdrawal may not meet your goal.
Save the order preview if you need a record of the quoted costs. Remember that a quote can expire before you confirm it, especially in a fast market.
Asset names can be similar, and some platforms list wrapped or network-specific versions. Verify the ticker together with the full asset name and withdrawal network. A low fee is irrelevant if the asset you receive cannot reach your intended destination.
