A broker: one quoted price, no order book
An exchange matches buyers and sellers against each other on an order book, and the price you get depends on what the book looks like at that exact moment. A broker skips that entirely: it holds its own bitcoin inventory, quotes you a single all-in price for the amount you want, and you either accept it or you don't. There's no bid, no ask, no depth chart — just one number.
That simplicity is the entire product. A broker's flow is usually three steps: enter an amount, see a price, confirm. No understanding of order types, no risk of a partial fill, no watching a live book move while you decide. The tradeoff is baked directly into that one quoted number: a broker's price is the underlying market price plus a markup, and because there's no visible book to compare it against, that markup is far less transparent than an exchange's bid/ask spread. Two brokers quoting the same amount at the same moment can differ by a percent or more, and the only way to know is to actually compare quotes — the interface doesn't surface it for you the way an order book's depth does.
Brokers are still companies, which means they're still custodial the moment you hand them money and until the bitcoin actually lands in a wallet you hold the key to — Chapter 8's rule applies exactly the same way it does to an exchange. And because moving money for other people in exchange for an asset is a regulated activity in most places a legitimate broker operates, expect identity verification here too; "no order book" isn't the same as "no KYC."
An exchange shows you the market and lets you negotiate with it. A broker just tells you the price. You're paying for not having to look.
Peer-to-peer: no company in the middle at all
Peer-to-peer removes the middle entirely — not just the order book, but the company. One person sells bitcoin directly to another, the price is whatever the two of them agree to (which can be at, above, or below the going market rate, since there's no book enforcing convergence toward one), and settlement is a direct on-chain transaction between two wallets. In its purest form it needs no platform at all: two people who already know and trust each other, or who simply meet in person, can do it with no account created anywhere.
That absence of a company in the middle is where P2P's two real advantages come from, and a broker or an exchange can't offer either one. First: no identity verification. A broker or exchange is a regulated business moving money on someone else's behalf, which is exactly why the broker section above still requires KYC despite having no order book — but a private trade between two people isn't a business transaction with a company in the loop, so there's no institution obligated to collect anyone's identity. Second, and easy to overlook: if the trade happens face to face with physical cash, the trust problem escrow exists to solve mostly evaporates on its own. Escrow protects against a sequential payment — one side pays, then waits, exposed, for the other to follow through. A cash-in-person trade is close to simultaneous: hand over the bills as the bitcoin arrives (or wait for it to broadcast before parting with the cash), and neither side is ever exposed the way a remote payment leaves them. Escrow is a fix for a specific problem — a payment method that doesn't settle instantly, between two people who've never met — not an inherent tax on P2P itself.
Most P2P activity today, though, happens through a platform connecting strangers who usually aren't meeting in person — a bank transfer, a gift card, or some other remote payment method that reintroduces exactly the timing gap cash sidesteps. The classic mechanism there is escrow: the seller's bitcoin is locked in a wallet neither party alone controls (often a multi-signature address requiring the platform's cooperation to release) until the buyer confirms payment arrived through whatever channel they agreed on. That solves the most obvious failure mode — a seller taking payment and never sending the coin, or a buyer claiming non-payment after receiving it — but it reintroduces a third party you're trusting to arbitrate fairly if the two sides disagree, a smaller, narrower version of the same custodial trust P2P was supposed to help you avoid in the first place. Many such platforms also require some identity verification of their own to operate legally, which quietly gives back part of the no-KYC advantage the moment a platform gets involved.
Paxful, once the largest escrow-based P2P bitcoin marketplace, is that narrower trust playing out at real scale. It suspended trading abruptly in April 2023 when a lawsuit and power struggle between its two co-founders drove off most of the senior team overnight, freezing the platform — though the company said funds themselves stayed accounted for — for millions of users with no warning. It relaunched months later under new leadership and a court-supervised cleanup, but the story wasn't over: in July 2024, one of the very co-founders behind the original collapse pleaded guilty to willfully failing to run the anti-money-laundering program U.S. law required of the platform. The compliance costs that plea left behind never really cleared, and in October 2025 Paxful announced it would wind down for good by November 1 — not from a hack, an insolvency, or a bad trade, but from years of fallout at the company itself. Every part of that story sat one layer above any individual trade going well or badly, which is exactly the "narrow intermediary" risk this chapter flags for escrow-mediated P2P — just at the scale of an entire platform instead of one transaction.
Left to right: less company involvement and no identity check, but more of the vetting and settlement risk is yours to carry — until a company enters the picture and takes both off your hands, at the price of trusting it and identifying yourself to it.
The honest way to think about P2P's cost isn't a fee line at all — it's risk, priced in effort, plus one genuine, non-price advantage: no company anywhere in the chain that could be compelled to hand over who traded with whom. In exchange, you take on your own diligence on a counterparty and, without an escrow layer, your own settlement instead of a platform's. That's a real cost even when no money and no ID change hands for it.
What actually differs, in one line each
A broker trades price transparency for convenience: one quote, one click, a markup you'd have to shop around to even notice, and identity verification exactly like an exchange's. Peer-to-peer trades intermediary trust for counterparty trust: potentially the best price available anywhere and no identity check required, purchased with your own vetting effort and, without an escrow layer or an in-person cash handoff, real exposure to the other person simply not holding up their end. Neither is strictly safer or cheaper than the other — they fail in different ways, for different amounts, for different people.
