MEXC vs Bybit 2026: One Has an EU Licence, One Was Robbed

Two facts decide more here than any bonus does. Bybit is authorised under MiCA and MEXC is not, and Bybit survived the largest theft in the industry's history by covering it. Fees compared with both schedules linked.

1. The two facts that separate these exchanges

Bonus programmes are the least interesting difference between MEXC and Bybit, and writing about them first is how most comparisons avoid the two things that actually distinguish the pair. Both are on the public record and they point in opposite directions.

Bybit is authorised in the EU. MEXC is not.

Bybit EU GmbH holds a crypto-asset service provider authorisation under Article 63 of MiCA, granted by Austria's Financial Market Authority on 28 May 2025 and passported across the EEA. It covers custody, exchange of crypto for funds, exchange of crypto for crypto, placing, and transfer services. It is listed on the FMA's own notice and in ESMA's register of authorised providers.

On MEXC, no register I checked shows an authorisation anywhere, and eight regulators have published warnings, including the Dutch AFM and Germany's BaFin. I earn a commission when someone signs up to MEXC through my link and nothing at all from Bybit, so let me put this plainly: on the question of authorisation in Europe, this comparison does not favour the exchange I am paid to promote.

Bybit was robbed of more than any exchange in history.

On 21 February 2025 attackers took over $1.4 billion from a Bybit multisig cold wallet, including 401,347 ETH. The mechanism was not a broken key: malicious JavaScript was injected into the wallet interface through a compromised developer machine, so the signers approved something other than what they were shown. It is attributed to the Lazarus group.

The outcome matters as much as the event. Bybit covered the loss, stated that client assets were backed one to one, kept withdrawals open, and users were made whole. That is what a well capitalised exchange surviving its worst day looks like, and it is a genuine data point in Bybit's favour rather than against it.

MEXC has no publicly disclosed breach of user funds. Read those two paragraphs together and you have the honest shape of this comparison: one exchange has been tested in public and passed, the other has not been tested in public at all. Those are not the same thing as being safer, and it is worth being clear about which one you are actually choosing.

2. Sign-up rewards

Both run rotating, task-based campaigns rather than a fixed welcome bonus, and both advertise a ceiling. MEXC's published programme totals Up to 8,000 USDT[src], of which the unconditional sign-up task is 20 USDT[src], with vouchers valid for 15 days[src]. I have taken that campaign apart task by task.

I have not read Bybit's current campaign terms, so there are no Bybit figures here. The general point from the guide on reading these offers applies to both: the headline is the sum of every task, most of which need deposits and volume you were never going to reach.

2. Trading Fees: Maker/Taker

Both use a maker-taker model, and the rates are not as similar as most comparisons suggest. On the standard retail tier MEXC charges half what Bybit does on the taker side. The figures below come from each exchange's own fee documentation, read on 23 August 2026 and linked — more detail in my MEXC fee guide.

Rates and terms change frequently. Verify current numbers on each exchange's official fee page before trading.

3. Futures & Derivatives

Bybit has historically been derivatives-first, with a strong reputation among perpetual and options traders. MEXC has expanded its futures line-up and runs frequent futures bonus campaigns — details in my MEXC futures bonus guide. If you mostly trade derivatives, look at each platform's current funding rates, insurance fund, and liquidation engine — not just the welcome bonus.

4. Altcoin Selection

MEXC is known for listing a very large number of newer altcoins, often earlier than most competitors. Bybit lists fewer pairs but focuses on higher-liquidity assets. Traders hunting early listings tend to favor MEXC; traders prioritising deep books and tighter spreads on major pairs often prefer Bybit.

5. Affiliate and referral programmes

For MEXC I can give real numbers because I am on the programme. The advertised maximum is 70%[src], the rate that applies when a period's targets are missed is 50%[src], and the upgrade between them requires holding 2,000 MX[src] alongside five qualifying referrals, or 20,000 MX[src] with no referrals at all. A referral only counts once their trading fees reach 5 USDT[src]. The full mechanism is in the affiliate guide.

Bybit runs separate affiliate and referral tracks. I have not verified its rates against Bybit's own documentation and will not print numbers I have not read.

6. What happens when something goes wrong

Both exchanges publish proof of reserves and both offer the standard controls: two-factor authentication, withdrawal whitelists, cold storage. Those are table stakes and they do not separate the two.

What separates them is recourse. If your account is restricted on Bybit in the EU, there is a named authorisation and a competent authority behind it. If it happens on MEXC, MEXC's own Risk Control Guideline allows restrictions of "up to 180 days (or longer)" and reserves the right to "transaction rollbacks and profit disgorgement", while the Seychelles regulator has said it is not in a position to help users recover funds. That comparison is set out in full in the safety review.

7. Which one, honestly

• If you are in the EU or EEA: Bybit holds the authorisation and MEXC does not. That is the single clearest finding on this page and it does not favour my affiliate link.
• If you want early altcoin listings: MEXC lists far more, and far earlier. That is a genuine reason people choose it, and it comes with the risk that goes with unproven tokens.
• If you trade spot frequently: the fee table above is the argument for MEXC, and it is a real one that compounds with volume.
• If you trade derivatives on majors: Bybit was built derivatives-first and has the deeper books on the large pairs.
• If you are picking on the sign-up bonus: it is the smallest number involved in this decision.

There is no universally better exchange here, but there is a clear answer to specific questions, and I would rather give you those than a verdict that happens to match where my commission comes from.
