Which exchange has the best sign-up bonus?
Don't just read the headline.

“Get $100 for signing up.” “Mystery boxes up to 60,000 USDT.” What matters is how much you actually receive, what you must do to get it, and whether you can use it.

What sign-up rewards do exchanges offer?

Common welcome rewards
RewardHow you get itWhat it's really worth
Mystery boxesComplete verification, deposit and trading tasksMostly small amounts; top prizes are rare
Trial fundsIssued after sign-up or tasksUsually limited to specific trades; only profits may be withdrawable
Fee vouchersFirst trade and similar tasksOnly offsets fees, and expires
Boosted earn ratesNew users, capped amount and daysSmall extra interest; the coin price still moves
Referral fee discountEnter a code at sign-upApplies to every trade, for life

The first four are one-off. The last one keeps working as long as you trade. You can have both.

Four things to check before chasing a bonus

  1. Requirements: how much must you deposit or trade?
  2. Withdrawability: trial funds and vouchers usually aren't cash.
  3. Expiry: many rewards vanish after 7–30 days.
  4. The platform itself: a big bonus from an unreliable exchange is worthless. Check track record, size and proof of reserves.

“Free crypto for signing up”: real or scam?

Two very different offers
Exchange welcome tasks“Free crypto” ads and DMs
Where you claimThe exchange app's Rewards HubUnknown sites, groups, DMs
Pay first?NoOften asked to deposit or “activate”
Can you withdraw?Per campaign rulesBalance shows, withdrawals never work
What's behind itCustomer acquisition budgetPonzi, gambling or scam platforms

If you must pay to claim, pay to withdraw, or recruit others to earn, treat it as a scam. Real exchange rewards never require you to send money first.

One-off bonus or lifetime discount: which is worth more?

What a 20% fee discount saves (OKX regular-user fees)
Monthly volumeTrade typeSaved per monthSaved per year
5,000 USDTSpot taker 0.10%≈ 1 USDT≈ 12 USDT
20,000 USDTSpot taker 0.10%≈ 4 USDT≈ 48 USDT
100,000 USDTFutures taker 0.05%≈ 10 USDT≈ 120 USDT
500,000 USDTFutures taker 0.05%≈ 50 USDT≈ 600 USDT

Honestly: occasional buyers save small amounts, active traders save a lot, and it repeats every year. A welcome box is a one-time surprise; the discount is the base. Take both. Try the savings calculator with your own numbers.

Best sign-up bonus: FAQ

Sign-up bonus
FAQ.

Which crypto exchange has the best sign-up bonus?

Compare requirements, withdrawability, expiry and the platform's reliability, not the headline figure. One-off rewards plus a lifetime fee discount is the full picture.

Are crypto sign-up bonuses worth it?

They're a nice extra, but most users receive small amounts. For regular traders, a permanent fee discount is usually worth more over time.

Is “free crypto for signing up” a scam?

Rewards in an exchange's own Rewards Hub are real. Offers from unknown sites that ask you to deposit or pay to withdraw are scams.

Can I withdraw the OKX sign-up bonus?

It depends on the reward type and campaign rules shown in the Rewards Hub; trial funds and vouchers usually can't be withdrawn directly.

Can I get welcome rewards and the referral discount?

Yes. Signing up with OK66688 doesn't affect new-user tasks or mystery boxes.
