Why the cheapest P2P advert is often fake — and how to spot one

Open the USDT/UAH buy page of a P2P marketplace sorted by price, and the first row is sometimes extraordinary. We have seen an advert offering USDT at ₴1.00 on a major exchange's hryvnia book while every honest seller around it asked about ₴46. Nobody is selling a dollar for 2 cents. That row exists to be clicked, not to be traded.

If you compare P2P prices by hand, or with a tool that simply takes the top of each book, adverts like this one will wreck your numbers. If you are doing P2P arbitrage, they will show you bundles that do not exist.

Two kinds of advert that should not set "the price"

Priced far outside the market

An advert priced far below every other seller — or far above every other buyer — is almost never a real offer. The usual reasons:

• Bait. The advert sits at the top of the list because of its price, catches your attention, and the order then goes wrong on purpose: the "seller" cancels, stalls, or tries to move you into a private chat.
• Fraud. Some are lures for schemes that only work outside the exchange's escrow — "the order is glitched, pay me directly and I'll send the coin."
• Mistakes. Occasionally someone simply typed the wrong number. Even then, it will be taken by somebody else within seconds of you seeing it.

Tradeable only in an amount too small to matter

The second kind is subtler. The price is good, and real, but the advert's limits are tiny — a few hundred hryvnia — or its available amount is nearly exhausted. It is often an honest advertiser with a low limit, not a scammer. But it tells you nothing about the price you can trade at, because it cannot fill your order.

Both kinds make the top of a book look better than the market really is. The difference is that the first is a trap and the second is simply irrelevant — which is why a careful tool flags both, but describes the flag as "low trust" rather than "scam".

How to check an advert in thirty seconds

1. Compare it with the rest of the book. Look at the next five to ten adverts. If the top one is far from all of them, it is not the market price, whatever it says.
2. Read the limits. Is the minimum below your amount and the maximum above it? Is there enough available?
3. Look at the advertiser. Number of completed orders, completion rate, how long the account has existed, a verified badge if the exchange has one. A brand-new account with three orders and the best price in the book is a pattern, not a coincidence.
4. Check the payment method. An advert that offers a method that makes no sense for the currency, or "any bank", deserves a second look.
5. Read the advert's terms. Instructions like "message me first" or "payment details in chat only" often precede a request to leave the platform.

Red flags once the order is open

Even a normal-looking advert can turn into a scam inside the order. Stop and contact the exchange's support if the other side:

• asks you to release the coin before the money is visible in your own bank account;
• sends a screenshot of a payment instead of a payment;
• pays you from an account in a different name than their verified one — this is how stolen money is passed through honest traders, and it is how cards get frozen;
• asks you to cancel the order and pay directly, or to continue on Telegram;
• pressures you with urgency: "quickly, my boss is waiting", "the price will change".

The rule that covers all of them: trade only inside the exchange's escrow and chat, and release only after the money has arrived.

What this means for comparing prices

Any comparison that takes the cheapest row of each book will be wrong exactly when it matters, because the cheapest row is the one most likely to be manipulated. The honest headline price is the cheapest advert that passes the checks above, not the cheapest advert.

This is how P2P View handles it. When it reads an exchange's book, it asks the server to assess each advert, and the server flags the ones priced far outside the book or tradeable only in an amount too small to matter. The flagged row stays visible — struck through and marked "low trust" — so you can see it was there, but it never becomes the headline price, and the bundle calculator never builds a chain on one. And if you decide a particular advertiser is not worth trading with, you can hide them yourself.

Flagged or not, the final check is always yours: look at the advertiser before you open the order.
