How to Spot Fake and Misleading Crypto Bonuses

Search for “free crypto sign up bonus” and you will find headlines worth thousands of dollars. Very little of that money ever reaches anyone’s wallet. Sometimes the reason is innocent: the headline adds up every possible reward for a whale trader, and the fine print says so. Sometimes it is not innocent at all: the “bonus” is bait to get your login, your seed phrase or a “withdrawal fee”.

This guide sorts offers into three groups. First, the legal but misleading bonuses that real exchanges run, with rewards you cannot withdraw or realistically unlock. Second, outright scams that borrow the language of referral programs. Third, a checklist you can run in five minutes before you sign up anywhere. Use it alongside our lists of verified sign-up bonuses and no-deposit bonuses, where we break down the real terms of each offer.

Why most “bonuses” are worth less than they look

An exchange bonus is marketing spend. The exchange wants you to deposit, trade and keep trading, so it designs rewards that only pay off if you do those things. That is fair as long as it is clear. The problem is the gap between the number in the banner and the number that ends up as money you control.

Three questions close that gap. Can I withdraw it? What do I have to do to unlock it? How long do I have before it expires? A $20 reward you can withdraw after one small trade is worth more than a $1,000 “package” of vouchers that expire after three days. Keep those questions in mind as you read the types below.

Non-withdrawable trial funds and bonus balances

Many exchanges credit new users with a trial fundBonus funds credited to your account that you can trade with but cannot withdraw. Usually only profits made with them can be kept, if at all. or bonus balance. It appears in your account with a dollar value, which feels like money. It is not. You can use it as margin or to cover fees, but you cannot send it to your wallet or bank. If your trade loses, the bonus absorbs the loss and disappears. If it wins, you typically keep only the profit, often up to a cap, sometimes only after more trading.

The exchanges are open about this in their own terms. OKX, for example, lists rebate cards, trial funds and contract experience coupons as fee offsets in its affiliate rules, and notes that trades paid with them generate no referral rebate. Bybit calculates referral commission on net fees, defined as trading fees minus bonuses, coupons and credits used. Both are a clear signal of what these balances are: discounts on future fees, not deposits.

Futures position vouchers

A position voucherA coupon that lets you open a leveraged futures position of a fixed size without using your own margin. The voucher is consumed or reclaimed when the position closes. is a trial fund aimed at derivatives trading. You get, say, a voucher to open a position worth a fixed amount at a set leverage. The voucher value is not paid out; only realized profit may be credited, usually with conditions attached.

The catch is leverage. Futures positions can be liquidated by small price moves, so a large share of position vouchers end in zero. Exchanges know this, and it is why vouchers often make up most of the headline in “up to $5,000” packages. If you have never traded futures, treat any futures bonus as worth roughly nothing, and read our explanation of maker and taker fees before you trade derivatives at all.

Fee-only coupons and rebate vouchers

The most common reward from big exchanges is a trading fee rebate voucher. Binance’s welcome rewards are a good example: up to $100 in vouchers that offset Spot trading fees. Binance’s own FAQ adds the conditions: rewards are issued only after identity verification, vouchers have to be redeemed in Rewards Hub, they cannot offset API trading fees, business accounts cannot redeem them, and the offer is not available in a long list of countries including the United States, the United Kingdom and Canada.

A fee voucher has real value only if you trade enough to pay that much in fees before it expires. At a 0.1% fee, using a $50 voucher in full means about $50,000 of trading volume. For an occasional buyer, most of the value evaporates. That does not make the offer fake, it makes it a discount, and you should value it as one.

“Up to” headlines and volume requirements

“Up to” is the most expensive phrase in crypto marketing. The headline usually adds together every task tier, and the top tiers require deposits or trading volume requirementsThe total value of trades you must make (buys plus sells) within a set period to unlock a reward. Trading $1,000 back and forth five times counts as $10,000 of volume. that only professional traders reach.

Look at how a typical tiered package breaks down:

When you evaluate an offer, add up only the tiers you would hit anyway. That figure, not the headline, is the real bonus. Volume tiers also push you to over-trade: paying 0.1% on $50,000 of trades to earn a $100 bonus costs you $50 in fees before any trading losses.

Expiry windows and claim deadlines

Almost every reward has two clocks. The first is the window to complete the task, often 7, 14 or 30 days from registration. The second is the time to claim or use the reward once you get it. Bybit, for example, puts referral rewards through a 3-day risk review and then gives you 10 days to claim them before they expire. Binance vouchers stay usable for only a few days after redemption.

Missing a deadline is the most common way people lose a perfectly real bonus. Set a reminder on the day you sign up, and do not redeem a voucher until you are ready to trade.

Deposit-lock bonuses

Some platforms, especially futures-focused ones, offer a percentage deposit bonus: deposit $500, get a $500 bonus. The bonus sits next to your deposit as trading margin. The condition hides in the terms: withdraw any part of your deposit, or transfer it out of the futures account, and the entire bonus is removed. Some versions also require you to reach a volume target before any of it becomes withdrawable.

These offers make your account look twice as large, which encourages bigger positions and higher leverage. If the bonus is clawed back during a drawdown, your effective margin shrinks at the worst moment. Read the withdrawal and clawback rules before accepting any deposit match.

Phishing “referral code” sites

Now the scams. A phishing referral site copies an exchange’s design, ranks for searches like “exchange name promo code”, and sends you to a fake login page. Once you type your email, password and two-factor code, attackers log in to your real account. Variants ask you to “connect your wallet to claim the bonus” and then request a signature that drains it.

Signs to watch for: a domain that is close but not exact (an extra letter, a hyphen, a different ending); search ads that lead to a page asking you to log in rather than sign up; and pages that demand a seed phrase or private key, which no exchange or bonus ever needs. Binance even says it voids commissions from links promoted through imitation websites, so a legitimate inviter has no reason to use one. Use the exchange’s official verification tool where it exists, such as Binance Verify, which checks URLs, emails, phone numbers and social accounts.

Fake airdrops and “free crypto, instant withdraw” offers

The other big family of scams promises free tokens. A message, comment or post announces an airdrop or a sign-up bonus you can withdraw immediately. To claim it, you either connect a wallet to a malicious site or create an account on an unknown platform. On the unknown platform, your balance shows hundreds or thousands of dollars, but the withdrawal needs a “fee”, “tax” or “unlock deposit” first. Pay it and the balance never moves.

The FTC’s guidance on cryptocurrency scams puts it bluntly: scammers promise free money, and only scammers guarantee profits or big returns. It also warns about impersonation of well-known companies and about investment managers who contact you out of the blue. Real airdrops do exist, but they are announced on the project’s official channels and never require you to send funds first. Our glossary explains how legitimate airdrops and points programs work.

The five-minute bonus checklist

If an offer fails two or more rows, skip it or value it at zero. If it fails the last row, report it.

What a fair bonus looks like

None of this means you should ignore bonuses. A fair offer is one where the terms are published on the exchange’s own domain, the reward type is stated (cash, voucher or fee discount), the conditions match what you plan to do anyway, and identity verification is part of the process. That last point surprises people, but KYC requirements for crypto bonuses are a sign the exchange is regulated and serious about stopping abuse. And always register through the official sign-up page with the code in place; our guide to using a referral code shows how.
