Crypto trading basics: orders, spreads, fees and sizing
Order types, spreads, fees and position sizing in plain English, plus the honest reasons beginners lose money when they actually start trading crypto online.
Trading crypto means buying and selling to profit from price moves, and the mechanics (order types, spreads, fees and how much you put on each trade) decide a lot of the outcome before your opinion on the price even matters. Learn the plumbing first. Then decide if you want to trade at all.
This page is education, not financial advice. We are not telling you to trade, what to buy, or when. We are explaining how the machine works so nobody can rush you through it.
Trading is not the same as buying
When you buy crypto on an Exchange and leave it alone, you are making one decision. When you trade, you are making many decisions, each with a cost attached. Every entry and exit has a price you might not get, a spread you pay, and a fee on top.
That distinction matters because the skills are different. Holding asks for patience and good security. Trading asks for a plan, discipline when the plan says “get out”, and a tolerance for being wrong in public with your own money. If that last part sounds miserable, you have learned something useful for free.
Order types: how you tell the exchange what you want
An order is an instruction. The type of order decides what you trade off: speed or price. FINRA’s investor guide on order types lays out the main ones, and crypto exchanges use the same ideas.
Market order. Buy or sell now, at or near the current price. FINRA notes a market order generally executes at or near the current bid or ask. You get speed. You do not get a guaranteed price, and in a fast market the fill can land somewhere you did not expect.
Limit order. Buy or sell only at your price or better. If the market never reaches your price, nothing happens. You get price control and accept that the order may never fill.
Stop order. A trigger. Once the price hits your stop level, the order becomes a market order. People use stops to cap a loss, but because the triggered order is a market order, the actual fill can be well past your stop in a sharp move.
Stop-limit order. The stop triggers a limit order instead of a market order. That protects your price, with the same catch as any limit order: it might not fill, and the loss you were trying to cap keeps running.
A simple habit helps. Before you press the button, say out loud which you care about more on this trade: getting in, or getting in at a specific price. That answer picks the order type.
Spreads: the cost you do not see on a receipt
Every market has two prices at once. The bid is the highest price a buyer will pay right now. The ask is the lowest price a seller will accept. The gap between them is the spread, and when you buy at the ask and sell at the bid, you lose that gap even if the price did not move at all.
Some apps fold a spread into the price they quote you. Coinbase’s own pricing disclosure says that on simple buy and sell orders it includes a spread in the quoted price, that the spread may vary for similar transactions, and that you can see it on the order preview screen. That is not a scandal, it is the business model. It does mean the “price” on the big button is not the market’s midpoint.
Spreads widen when Liquidity is thin: small coins, odd hours, sudden news. Thin markets are also where a single Whale order can shove the price around. If you trade small coins, expect to pay more just to get in and out.
Fees: maker, taker and why frequency hurts
Most exchanges also charge a trading fee. Many use a maker-taker model. Kraken’s published schedule is a typical example: it runs maker-taker tiers based on your trading volume, and at every tier shown the taker fee is higher than the maker fee.
In plain terms, a maker is someone whose order sits on the order book waiting (usually a limit order that does not fill instantly), adding liquidity. A taker is someone whose order fills immediately against an order already sitting there, which is what a market order does. Exchanges reward makers because resting orders make the market work.
The bigger point is frequency. FINRA’s day-trading disclosure says day trading generates substantial commissions even if the per-trade cost is low, and that total commissions add to your losses or reduce your earnings. A fee that looks tiny per trade becomes a real drag when you trade often. Add the spread on both ends and every round trip starts in a hole.
Position sizing: the decision that keeps you in the game
Position sizing is how much money you put into a single trade. Beginners obsess over what to buy. People who last obsess over how much.
The logic is simple. If one trade can wipe out a big chunk of your account, a normal losing streak can end your trading entirely. If each trade risks only a small slice, you can be wrong several times in a row and still be standing. You decide the slice in advance, write it down, and do not raise it because you “feel sure this time”.
Sizing connects to your stop. Decide where you would admit you were wrong before you enter, then size the position so that being wrong at that level costs only your chosen slice. Remember from the order-types section that a stop can fill past your level in a fast move, so leave room for that. Volatility in crypto means that room should be bigger than you think.
Avoid leverage while you are learning. The CFTC notes that profits and losses from volatility are amplified in margined futures, and losses can exceed your initial investment. Borrowed money removes the floor under your mistakes.
Why beginners lose money
There is no secret villain here, mostly just predictable habits.
- Trading too often. Each trade pays a spread and a fee. Frequency turns small costs into the main event.
- No exit plan. Buying is easy. Knowing in advance when you would sell, at a loss or a gain, is the hard part.
- Sizing up after a win. A lucky trade feels like skill and invites a bigger bet right before the next loss.
- Revenge trading. Trying to win back a loss immediately leads to rushed entries and bigger positions.
- Chasing hype. By the time a coin is all over your feed, the people who bought early are often the ones selling to you.
- Leverage. It shortens the distance between a bad idea and an empty account.
- Platform risk. The CFTC warns some platforms lack critical safeguards and may sell from their own accounts at customers’ expense. Where you trade is part of the risk.
Notice that none of these are about being bad at predicting prices. They are about costs, plans and behaviour, which are the parts you actually control.
A sane way to practise
If you want to learn trading, shrink the stakes until the lesson is cheap. Write a one-page plan: what you trade, when you enter, where you exit, your size per trade, and a hard monthly limit on losses. Keep a log of every trade with the reason you took it. Review it weekly.
Many people discover from that log that they would have been better off doing less. That is a fine result. Our strategies hub covers calmer methods, including buying on a schedule, that need far fewer decisions.

Questions people ask
What is the difference between a market order and a limit order?
A market order fills at or near the current price, so you get speed but not a guaranteed price. A limit order only fills at your price or better, so you get price control but no guarantee it fills at all.
Is the spread a fee?
It works like one. On simple buy and sell screens, Coinbase says the spread is built into the quoted price rather than shown as a separate line. Check the order preview before you confirm.
Why does a stop order sometimes fill far from my stop price?
A stop order turns into a market order once the stop price is hit. In a fast market the next available price can be well above or below the level you set.
How much of my money should I trade with?
Only money you can lose completely without it touching rent, savings or debt payments. FINRA's day-trading disclosure says to be prepared to lose all the funds you use for day trading.
Do I need to trade at all to own crypto?
No. Buying and holding on a schedule is a different activity from trading. Many beginners never need an order type more complex than a basic buy.
