US Crypto Regulation: Why Licensed Exchanges Matter

What a money-transmitter license is

A money-transmitter license is a state-level license required to move, transmit, or hold customer funds. In the US, crypto exchanges that let you buy, sell, and hold crypto are generally treated as money transmitters, so they must register with the federal FinCEN as a Money Services Business (MSB) and obtain licenses in the states where they operate.

This is why a crypto exchange's US availability is not uniform — an exchange may be licensed in some states but not others, and some features or coins can vary by state. When a review says an exchange is "US-licensed," it means it has cleared this state-by-state money-transmitter regime, not just that it accepts US customers.

Why a US license matters

An exchange that is not licensed to serve US customers is operating outside the US regulatory framework. That carries real risks for you:

• No state oversight — a licensed exchange answers to state regulators; an unlicensed one does not.
• No clear custody rules — licensed exchanges must follow rules about holding and safeguarding customer funds.
• Recourse is harder — if an unlicensed exchange fails or freezes withdrawals, you have far fewer legal protections.

This is why this site only monetizes US-licensed exchanges (Coinbase, Kraken, Gemini, Robinhood Crypto, Crypto.com, Bitstamp) and lists international-only exchanges like OKX as information only.

Broker vs exchange

Not all crypto platforms are the same kind of business, and the difference affects how you trade:

• Exchange (e.g. Coinbase, Kraken, Gemini) — matches buyers and sellers on an order book. You can place limit orders, see the order book, and trade at the market price. Fees are typically maker/taker.
• Broker (e.g. Robinhood Crypto) — executes trades for you, often with a simpler interface and no order book. The cost is usually built into the spread rather than a visible fee. Robinhood is a registered broker-dealer (its parent), so crypto trades happen through a different model than a pure exchange.

Neither is inherently better — an exchange gives you more control and transparency on fees; a broker is often simpler for a first purchase. The right choice depends on how you trade.

The SEC, CFTC, and FINRA

Three federal bodies shape the US crypto landscape:

• SEC — the securities regulator. It decides which crypto assets count as securities and sets listing standards for exchanges that offer them. Its 2026 proposed framework (Release 33-11412) is the current reference point for how crypto assets are treated.
• CFTC — the derivatives regulator. It oversees crypto derivatives (futures, options) and treats some assets, like Bitcoin and Ethereum, as commodities.
• FINRA — the self-regulatory body for broker-dealers. It governs firms like Robinhood that offer crypto alongside securities.

The practical takeaway: a US exchange's regulatory footprint is a mix of state money-transmitter licenses plus federal registration. That footprint is a big part of why we rank regulation first in our review methodology.

What this means for your choice

When you compare exchanges, regulation is not a footnote — it is the first filter. A low-fee exchange that is not licensed for your state is not a bargain; it is a risk. Start with the US-licensed exchanges we rank, confirm availability for your state, and only then compare fees and features.
