How to Tell if a P2P Merchant Is Trustworthy

In P2P, the platform guarantees whether the trade completes; it doesn't guarantee the money on the other side is clean. So "choosing the right merchant" is basically "putting your risk on the right person." The good news: every merchant's page carries a few public numbers, and those are your basis for judging. This piece walks through volume, completion rate, account age and price spread one at a time, then how to combine them — plus the signals the numbers can't show. (All of this assumes Binance is available where you live; check that first.)

The four numbers at a glance

Here's a quick reference before the detail. Everything in it is a relative, qualitative read, not an absolute verdict — the actual picture depends on the specific counterparty and the platform's rules at the time, so treat it as a first filter, not a guarantee.

Signal	What it tells you	How to read it
Volume / total orders	How much real trade the market has put through them	Higher and longer-running is steadier; barely any history is wider exposure
Completion rate	Whether they actually finish orders they accept	Consistently high is good; noticeably low — skip it
Account age	How long they've been active and watched by the platform	Older with a stable reputation is lower incentive to misbehave
Price spread	The one signal you read in reverse	Close to market is fine; clearly below the pack is a red flag

Note

This table compares relative trade-offs; it hands no single number a safety guarantee. Good numbers are past reputation, not a promise about this specific trade — always read them together and pair them with the behaviour signals further down.

Volume and account age: time-tested is steadier

These two go together because they measure the same thing — how long the market and the platform have tested this merchant. A merchant with large cumulative volume, whose account has been active a long time, has been through a lot of real trades and long sat inside the platform's oversight. Time is the hardest thing to fake; an older account with a stable reputation has both less incentive and a higher cost to misbehave.

Conversely, a brand-new account with barely any completed orders isn't necessarily bad, but you've no history to lean on — you'd be betting on a counterparty you know nothing about. As a beginner, tipping the scales toward "high volume, long age" is the best value-for-effort risk move there is. Once you're fluent with the flow and your judgement is sharp, you can consider newer merchants with good terms — no rush before then.

Completion rate: do they close cleanly

The completion rate reflects the share of orders this merchant actually finishes after accepting them. High means they take an order and do it properly — no fussing, no cherry-picking, smooth flow. Low often means they cancel at the last minute, pick and choose, or the trade tends to hit snags. A steady, reliable merchant usually keeps this high. See one that's clearly low and you don't need to agonise over why — skip it and move on. You're under no obligation to be the one who trials it.

Safer approach

Volume, account age and completion rate are the "positive" numbers — the better they are, the more the merchant has stood up to time and the market. But none of them is foolproof at the top end; read them alongside price spread below.

Price spread: suspiciously cheap is danger, not a deal

Price is the one number you read backwards. Slightly below market with everything else normal is fine to consider. But if a merchant's price is clearly below the pack, treat it as a red light, not a green one. The reason is direct: people rushing to convert dirty money, and runner outfits offloading, commonly use a tempting low price as bait, aimed exactly at buyers who only watch price. The bit you'd save is nowhere near proportionate to the risk of your account being caught in the money trail and frozen or closed.

Note

"Cheap" isn't neutral in P2P. A price clearly below the market more often corresponds to dirtier fund sources. On a first buy, pay a little more for the steady option rather than gambling on a freeze to save a sliver.

How to use the four numbers together

Any single number read alone skews. The right approach is to put all four side by side and see whether they corroborate each other. An ideal merchant looks like this: large cumulative volume, account active for a long time, completion rate held high, and a price close to the market rather than oddly low. When all four line up, you can settle down a fair bit.

Turn it around: any one clearly out of line is worth a second's pause. Low completion rate — don't touch. Absurdly cheap — don't touch. Very new but with terms too good to be true — set it aside as a beginner. It sounds simple, and done enough it becomes muscle memory that screens out most unsuitable merchants at a glance. If you'd like to turn this scoring logic into a tool that gives you a result directly, use the merchant score tool — enter a few numbers and it gives you a combined read.

From the editors

Here's a concrete move from how we pick merchants: open the list, and instead of rushing to compare prices, sort by price and mentally cross out the very cheapest band — skip it, don't even look. Among the rest, whose prices fall inside the normal range, click through one by one to check volume, account age and completion rate. Do it the other way — hunting inside the cheap pile first — and you're easily hooked by a merchant whose "numbers aren't bad and the price is great," which is precisely the combination to be most wary of. Clear the mines first, then pick carefully — that order is itself a filter.

Beyond the numbers: how the merchant talks

Good numbers are only the entry ticket; the merchant's behaviour during the trade matters just as much, and that part the numbers can't show. A legitimate merchant follows the platform's rules honestly — they won't ask you to transfer privately off-platform, won't ask you to change your payment reference, won't rush you to "confirm release quickly." Any of those moves should trip an alarm no matter how pretty the numbers are: numbers are past reputation, the script is present intent, and the latter tells you more about this trade's real risk.

FAQ

Which P2P merchant number matters most?

There's no single most-important number — read them together. Volume and account age show how long the market has tested the merchant; completion rate shows whether they close trades steadily; price spread is a reverse signal — suspiciously cheap is usually danger, not a deal. Judged together they're far more accurate than fixating on one.

Is a cheaper merchant always better?

No. Slightly below market with otherwise normal numbers can be considered, but a price clearly below the pack deserves caution. Dirty money offloading and runner outfits often use a low price to attract buyers, and that gap isn't worth the risk of your account being caught up and frozen.

Can I try a new merchant with a good price?

As a beginner, it's not advised. A short account age means you have no history to lean on, so your risk exposure is wider. Wait until you're fluent with the flow and your judgement is sharp. Early on, favour older merchants with high volume and a stable reputation.

The numbers all look good — anything else to watch?

Yes. Good numbers are only the entry ticket; the merchant's behaviour during the trade matters just as much. Anyone steering you off-platform, asking you to change the payment reference, or rushing you to release early deserves an alarm no matter how good the numbers — these are danger signs the numbers can't show.
