A crypto exchange rarely charges a single, obvious price for a trade. The headline rate is one layer, and the rest are collected in ways that do not appear on the confirmation screen. Reading a fee schedule before funding an account is the difference between a predictable cost and a surprise.
Maker and taker fees
Most order-book venues split trading fees in two. A maker order adds liquidity by sitting on the book until someone fills it, and is charged less. A taker order removes liquidity by matching an existing order immediately, and is charged more. Market orders are almost always taker orders, so the convenience of an instant fill carries the higher rate.
Published rates are often tiered by 30-day volume: the more you trade, the lower the percentage. A schedule that advertises its lowest tier is quoting a fee most users will never reach.
The spread is a fee too
On a "no-fee" or instant-buy product, the cost is moved into the spread — the gap between the price to buy and the price to sell at the same moment. A wide spread can exceed a conventional trading fee several times over while showing 0% on screen.
Deposits, withdrawals and networks
- Fiat deposits by card usually cost more than by bank transfer.
- Crypto withdrawals carry a flat network fee that the venue sets, and it can differ sharply from the actual on-chain cost.
- Moving an asset over the wrong network can strand it, which is not a fee but is a real, avoidable loss.
Working out the real cost
Add the trading fee, the spread and any withdrawal charge for the amount you actually intend to move, not the headline percentage. A venue that is cheap to trade on can be expensive to leave.
