Buy Rate vs Sell Rate: Why Crypto Apps Show Two Prices

Walk past any bureau de change and you'll see two numbers on the board for the dollar: one for buying, one for selling. Nobody thinks the operator is cheating. You know they buy your dollars for a little less than they sell dollars for, and that gap is how the business pays its way.

Crypto apps work the same way. Yet when an app's sell rate comes in lower than a figure someone posted in a WhatsApp group, plenty of people assume something's wrong. Usually it's just the two-price system at work, and understanding it helps you get more naira.

Two prices, two directions

• Buy rate: the naira you pay per coin when you buy from the platform.
• Sell rate: the naira the platform pays you per coin when you sell.

The buy rate is always the higher of the two. If you're selling, the buy rate is irrelevant to you, and the other way round.

Somewhere between them sits the mid-market rate, roughly where the wider market is trading. Neither of an app's two prices is the mid-market rate. Each sits a little to one side of it.

What the spread pays for

The gap between the buy rate and the sell rate is the spread. It isn't all profit. A platform that buys and sells crypto for naira has to:

• keep stocks of both crypto and naira, so it can pay you straight away;
• carry price risk, because crypto and the naira can both move while it holds them;
• cover transfer costs for paying naira to banks and moving crypto between wallets;
• pay staff, keep systems running and make a margin.

Spreads usually widen when markets are jumpy, and for coins that trade less often, because the platform's risk is bigger. They narrow when markets are calm and busy.

Spread vs fees: a worked example

A narrow spread is good, but it isn't the whole story. Some apps advertise a tight rate and add fees on top.

These numbers are invented to show the maths. They don't come from any real app. Say the mid-market rate is ₦1,000 per USDT, and you want to sell 300 USDT.

	App A	App B
Buy rate	₦1,015	₦1,008
Sell rate	₦985	₦992
Selling fee	None	1%
Withdrawal fee	None	₦100
Naira from selling 300 USDT	₦295,500	₦294,524

App B has the narrower spread and the better-looking sell rate. It still pays you ₦976 less, because its fees take back more than its rate gives.

The table shows something else too. If you bought 300 USDT on App A and sold it straight back, you'd pay ₦304,500 and receive ₦295,500: ₦9,000 gone on the round trip before the price has moved at all. That's one reason frequent flipping between naira and crypto quietly eats into savings.

If you want a single number for comparing spreads, turn the gap into a percentage: subtract the sell rate from the buy rate, divide by the mid-market rate and multiply by 100. In the example, App A's gap is ₦30 (₦1,015 minus ₦985), and 30 ÷ 1,000 × 100 = 3%, which matches the ₦9,000 round trip on 300 USDT worth ₦300,000 at the mid-market rate. App B's spread is 1.6%. Just remember that the percentage ignores separate fees, which is exactly what tripped up App B.

Why the rate you saw online isn't what you'll get

A rate in a group chat or an X post can be off for several ordinary reasons:

• It's the buy rate. The higher number is the one that looks good in a screenshot.
• It's old. Rates move through the day as crypto prices and the naira move.
• It has conditions attached. It may be for a large amount only, or from a P2P ad with a minimum order, a particular bank or a slow buyer.
• It's a different market. An official or bank dollar rate isn't a crypto rate. Our post on why the naira rate on crypto apps differs from the CBN rate explains the gap.
• It's bait. A rate far better than everyone else's is a classic opening for scams, especially from "buyers" who want to trade outside a platform. Our guide to avoiding P2P scams covers the usual tricks.

The only rate that matters is the one you get, for your amount, at the moment you confirm.

How to compare apps properly

1. Pick your amount, for example 300 USDT.
2. Open each app's sell screen and enter that same amount.
3. Write down the final naira figure each one shows after fees.
4. Subtract the network fee you'll pay to send the crypto there. It depends on the network, so check the fee your wallet or exchange shows before you send.
5. Check for withdrawal charges if they aren't already included.
6. Do it all within a few minutes, because rates move.

How it works on KWIQ

• Selling: swapping crypto to naira on KWIQ has zero fees, and the app shows the rate and the naira amount before you confirm. The figure on the screen is the figure you're agreeing to.
• Buying: KWIQ's app also lets you buy crypto. Check the current buy rate in the app before you confirm.
• Getting paid: withdraw to any Nigerian bank account, including OPay, PalmPay, Kuda, Moniepoint and all commercial banks. Once you sell, naira can reach your account in as little as 4 seconds.

Check the number that counts

Next time a "rate" lands in your group chat, open an app and look at the real figure for your amount. Download the KWIQ app to see KWIQ's naira amount for your crypto and compare it with the rest. If your phone is low on space, you can also create a free account on the web.
