Which order type should I use?
No order type is “better” — there are only ones that fit what you are trying to do this time. So every recommendation below states what you give up, not just what to pick.
1. What is this purchase for?
2. Relative to your normal spending, this amount is
3. Would you pay slightly more to have it done now, or rather wait?
One-click buy = fewest steps, paid for with price.
Market order = certainty of filling, paid for with price.
Limit order = certainty of price, paid for with time.
The mechanism underneath — how the order book matches you — is drawn out in market or limit order. Read that once and you will not need this tool again.
Static version: just look it up#
| Your situation | Use | What it costs you |
|---|---|---|
| First purchase, small amount | One-click buy | Markup of about 1–2% versus spot. Buys you the fewest steps and the fewest ways to go wrong — worth it the first time |
| Done it before, just want to buy | Limit order, just above market | Almost nothing. The most practical everyday combination — near-certain instant fill plus a price ceiling |
| Want it now, do not want to think | Spot market order | Price is whatever the market gives you (slippage). On BTC at small size this is negligible |
| Have a target price and can wait | Limit order at your target | It may never fill. You could watch the price move away from you |
| Larger amount | Several small limit orders | More effort and more time. Avoids eating through the order book in one go |
All of the above assumes you are on the spot screen. If the page shows leverage multipliers (5×, 10×, 100×), long/short buttons, margin or a liquidation price, you are on derivatives, not buying.
The test: buying does not require you to choose a multiplier. See the first common mistake.
Three numbers to check before confirming#
-
The ticker is right
BTC, not something else with BTC in the name.
- You counted the decimal places
-
The quantity makes sense
Quantity times current price should be roughly what you meant to spend.
