How to Pick an Exchange That Won't Run Off
A Beginner's 6 Screening Criteria

For a beginner, picking an exchange is more foundational than picking which coin — and more critical. Because the money you deposit is, in essence, held in custody by that platform. If it one day won't open, won't process withdrawals, or runs off with the funds, a bad market call costs you a small loss at most, but this can wipe you out entirely.

How do you steer clear of platforms prone to running off? You don't need to perform some deep due diligence. Remember the 6 easy criteria below, check them off one by one, and you'll filter out the vast majority of high-risk options and find yourself a steady starting point.

Criterion 1: A large enough user base

Lots of users is itself a plain safety cushion. An exchange with a huge user base has been tested broadly over a long time, and it can't quietly abscond — too many eyes are on it. Conversely, a small platform you've never heard of, with sparse users, carries much higher odds of trouble and much harder recourse if something goes wrong. So the simplest and most effective rule is to favor the handful with the largest user bases worldwide.

Criterion 2: Enough years of operation

Time is the hardest thing to fake. A platform that has run steadily for years, weathered several market cycles (survived the bear markets too), and is still standing has shown its funds and risk controls can take the strain. Many of the platforms that ran off had lifespans of only a few months: open up, draw a crowd, harvest, vanish. Checking how long an exchange has been founded and operating filters out a whole swath of flash-in-the-pan scam platforms — Mt. Gox in 2014, and the 2022 wave that took down Celsius, are the cautionary tales here.

Criterion 3: It holds licenses

A reputable large exchange usually applies for and holds the relevant licenses or registrations in certain countries or regions and submits to local supervision — in the U.S., that means money-transmitter licenses overseen by FinCEN and the states (New York's NYDFS BitLicense being the strictest), with the SEC and CFTC active around the space. This can't guarantee everything is flawless, but it at least shows the platform is willing to put itself under the constraint of rules, rather than being a no-name platform drifting entirely outside oversight. Willingness to accept supervision is itself a signal worth weighing.

Criterion 4: It has proof of reserves (PoR)

Proof of reserves (PoR) is a way for an exchange to demonstrate to users that it actually holds enough assets to cover everyone's deposits. Put plainly, it's the platform offering some verifiable means of telling you: user funds are really there, fully matched, not misappropriated or short. Many exchanges publish these as Merkle-tree attestations you can check against your own account.

A platform willing to publish proof of reserves is usually more transparent and better able to withstand a run. This criterion doesn't require a beginner to grasp the technical detail — treat it as a plus. A platform willing to prove the money is still there beats a vague, evasive one any day. The reason this metric exists at all is the FTX collapse, where a top exchange turned out to be missing the customer funds it claimed to hold.

Criterion 5: Smooth withdrawals, good reputation

This one is the most down-to-earth: whether you can actually get your money out is the most direct test of whether a platform is sound. A common precursor at troubled platforms is that withdrawals start getting slow, difficult, and delayed with every kind of excuse. So before committing, search what real users say about whether withdrawals go smoothly at this exchange; and when you do start using it, withdraw a small amount first to test the channel before putting more in.

Criterion 6: It doesn't promise you returns

The last criterion you use in reverse: a legitimate exchange will not promise you steady or principal-protected high returns. What it offers is the platform service of buying, selling, and custody; whether you profit depends on the market and your own decisions. If a platform opens with "30% annual yield on deposited coins" or principal-protected wealth-management pitches to lure you, that's often not an exchange at all but a Ponzi scheme wearing an exchange's coat — the BlockConnect-and-Celsius-Earn pattern. This single criterion alone helps you see through plenty of traps at a glance.

Run through these 6 and the steady starting point becomes clear: a mainstream large exchange that meets them. They have large user bases, years of operation, licensing and reserve disclosures, withdrawal reputations that hold up to scrutiny, and they won't promise you returns. Binance, OKX, and Bybit all fall in this tier; how to choose among them and who each suits is covered in our comparison of the three; and if you're simply worried about whether Binance is safe or might collapse, there's a dedicated piece answering that head-on. For a beginner, starting from such an exchange means you've already pressed the platform-running-off risk to its lowest. Once chosen, you can follow our first-purchase flow step by step, and don't forget to figure out whether your coins belong on a CEX or in your own wallet.

The 6 criteria in one sentence

You don't need to memorize jargon. String the 6 into one line: pick an exchange that's popular, has lived a long time, accepts supervision, dares to prove the money is still there, processes withdrawals smoothly, and doesn't con you with promises of steady profit. Anything that runs the other way — no one's heard of it, origin unknown, hiding from regulators, stalling withdrawals, opening with principal-protected high returns — however pretty the interface, cross it off. Before you act, run the pre-flight readiness checklist to confirm you're ready, then take the first step.
