On October 31, 2008, the Bitcoin whitepaper was published. 18 years later, we're celebrating with Bitcoin Whitepaper Days.
From October 30 to November 12, part of the fee you pay for crypto purchases and fiat deposits comes back to you in BTC. More of your money stays in crypto, not in fees.
How much BTC you get back
It depends on whether you've bought or deposited on CEX.IO before:
25% fee rebate for the first crypto purchase OR fiat deposit
3,5% fee rebate for repeated crypto purchases and fiat deposits
New here? Your first transaction gets 25%, and every one after that still gets 3,5%.
There's no cap on how much BTC you can get back. No luck involved either: every eligible user gets their rebate.
How to get your BTC back
In the CEX.IO App or on the CEX.IO website, buy crypto using a fiat payment method, or make a fiat deposit with any available fiat payment method.
We calculate your fee rebate automatically. You'll get an in-app notification when it's ready to claim.
Open the Reward Center in the CEX.IO App and claim your rebate. The BTC is credited to your CEX.IO account.
No sign-up to the promo campaign is needed. Each qualifying transaction gives you one rebate.
3 steps to your BTC
Buy crypto, or deposit fiat with your card or another payment method.
Wait for the notification. We calculate your rebate automatically.
Open the Reward Center in the CEX.IO App and claim your BTC.
That's it. No sign-up needed, and each buy or deposit brings its own rebate.
Here’s what this looks like
First-Timer Boost: If you spend $50 in fees on your first buy, you collect a $12.50 BTC rebate.
The Repeat Trader Loop: If you pay $50 in fees, your rebate is $1,75 in BTC. Keep buying, keep depositing, keep receiving rewards. Every move puts Bitcoin back in your pocket until November 12.
Before you start
Dates: October 30 – November 12, 2026.
Account: you'll need a fully verified CEX.IO account.
What counts: fiat deposits and crypto purchases paid with fiat, in the app or on the website. If a transaction is cancelled, reversed or charged back, its rebate is reversed too.
BTC amount: based on the BTC market rate when your transaction is processed.
Where it's available: wherever CEX.IO provides service and the promo is allowed by law. Check the list of supported countries and territories.
Quick answers
I'm new. What counts as my "first" transaction? Your first crypto buy or fiat deposit on CEX.IO ever. If it happens during the promo, it gets 25% back.
Do my next transactions count too? Yes. Every buy or deposit after your first gets 3,5% back in BTC, until November 12.
Is there a limit? No. No minimum amount, and no cap on the total BTC you can get back.
Do I need to join the promo? No. Just buy or deposit as usual, then claim your BTC in the Reward Center.
I don't see my rebate. What now? Wait for the notification first. If it still doesn't show up in the Reward Center, our support team can help.
Can I withdraw the BTC? Yes. Once you claim it, it's yours to hold, trade or withdraw.
Do I pay taxes on it? You may. Taxes on rebates are your responsibility. Where the law requires it, we may ask for tax forms (like Form W-9) and send tax reports (like Form 1099).
