MEXC vs BigONE: Fees, Trust Scores, and How BigONE Handled Its 2025 Hack
MEXC is the cheaper venue for spot traders, charging 0% maker and 0.05% taker against BigONE's 0.2% on both sides at its base tier, and CoinGecko rates MEXC 9/10 against BigONE's 5/10.
BigONE's futures fees match the majors, and after its July 2025 hot-wallet hack it pledged to cover every user loss.
Key Takeaways
- MEXC is our pick for spot trading, at 0% maker and 0.05% taker against BigONE's 0.2% and 0.2% at its Bronze base tier.
- A 10,000 USDT spot round trip costs about 40 USDT on BigONE's base tier and 5 to 10 USDT on MEXC, depending on whether you enter with a limit order.
- BigONE lost about 27 million dollars from a hot wallet on July 16, 2025, said private keys were not compromised, and pledged to cover all user losses.
- BigONE's futures schedule of 0.02% maker and 0.06% taker is fixed across tiers, while MEXC's BTCUSDT Special Rate is 0% and 0.02%.
- CoinGecko scores MEXC 9/10 and BigONE 5/10, and neither shows a recorded incident in its current 12-month window.
- MEXC documents up to 500x on BTCUSDT and ETHUSDT, against the 100x ceiling BigONE publishes.
A BigONE user reading about the 2025 hack usually has two questions: did BigONE stand behind its users, and what does it cost to keep trading there?
The first has a public record, and the second has a number.
This BigONE vs MEXC comparison answers both, starting with the cost.
Is MEXC Cheaper Than BigONE?
For spot traders, yes.
BigONE charges 0.2% to makers and takers at its Bronze base tier, while MEXC charges 0% and 0.05%, so a 10,000 USDT buy-and-sell costs about 40 USDT on BigONE and 5 to 10 USDT on MEXC.
Every round trip on BigONE's base tier pays the fee twice, once to enter and once to exit.
MEXC charges nothing on the leg you place as a limit order and 0.05% on the leg you take from the book, per the official MEXC fee page.
Buy 10,000 USDT of BTC and sell it later, and BigONE's base tier charges 20 USDT on each leg, 40 USDT in total.
On MEXC, a limit entry and a market exit cost 5 USDT, and two market orders cost 10 USDT.
Ten such round trips a month cost 400 USDT on BigONE's base tier and 50 to 100 USDT on MEXC.
BigONE lowers its spot rate at higher VIP tiers, so large accounts there pay less than the Bronze figure.
MEXC's full fee schedule, covering spot, futures and withdrawals, is set out in our fees guide.
The MEXC View
This site is operated by MEXC, so the view below is ours, and it starts with where BigONE holds up.
BigONE's futures fees match the majors at every tier, it pledged to cover user losses after its 2025 hack, and it said deposits and trading would resume within hours of that incident.
Our case rests on cost and trust signals: MEXC's spot schedule is cheaper for every order type, and MEXC scores higher on CoinGecko's Trust Score.
If you mainly trade perpetuals at BigONE's fixed rates and value the Kazakhstan licence BigONE cites, the gap is narrower than it is on spot.
How Do MEXC and BigONE Compare on Fees, Leverage, and Trust?
The rows follow our exchange review methodology, with BigONE's 2025 incident shown next to its response rather than on its own.

What Happened in the BigONE Hack, and How Did BigONE Respond?
On July 16, 2025, BigONE confirmed losing about 27 million dollars from a hot wallet in what SlowMist described as a supply-chain attack on its production network.
BigONE said private keys were not compromised and pledged to cover all user losses from its reserves and external borrowing.
The Block listed the losses as 120 BTC, 350 ETH, 1,800 SOL and about 8.54 million USDT across four networks.
SlowMist's alert said the attackers altered the operating logic of account and risk-control servers rather than stealing keys, as Cointelegraph also reported.
BigONE said deposits and trading would resume within hours, while withdrawals waited for further security work, per CoinDesk.
BigONE's separately operated Eurasia platform said on July 18, 2025 that it had not been affected and that its withdrawals were running again.
For how this incident sits among other exchange breaches, see our crypto exchange hacks database.
Is BigONE Licensed, and What Is MEXC's Status?
CoinGecko's regulation panel lists a Kazakhstan AIFC financial services licence for BigONE covering custody, exchange, clearing and dealing, and a June 2026 industry profile cites the same Kazakhstan licence.
CoinGecko notes that this panel is compiled with AI assistance, so the Astana Financial Services Authority's public register is the place to confirm the current scope.
MEXC holds no MiCA authorization in the EU and EEA, and the Dutch AFM lists it on its register of non-compliant entities.
Readers who need a licensed venue where they live should start from their own regulator's register rather than from either exchange's marketing.
MEXC's official country list sets out where the platform is available and which regions it restricts or limits.
How Do BigONE and MEXC Compare on Futures?
BigONE's futures rates are 0.02% maker and 0.06% taker at every tier, level with the majors.
MEXC's BTCUSDT Special Rate is 0% and 0.02%, though some of MEXC's standard pairs carry takers above 0.06%, and MEXC's API futures orders use a separate 0.06% maker and 0.08% taker schedule.
On leverage, MEXC documents up to 500x on BTCUSDT and ETHUSDT in its official 500x announcement, against the 100x BigONE publishes.
MEXC does not offer that tier in ten countries and territories, the United Kingdom and Canada among them, and copy trading cannot use it.
Our wider guide shows how the major derivatives platforms compare on fees, pairs and leverage.
How Do BigONE and MEXC Compare on Trust Checks?
CoinGecko scores MEXC 9/10 and BigONE 5/10, and neither shows a recorded incident in its current 12-month window.
CoinGecko tracks reserve data for both, and MEXC also publishes its own proof-of-reserves report.
CoinGecko's Trust Score methodology weighs liquidity, regulation, cybersecurity, incidents and proof of reserves, and BigONE's July 2025 incident now falls outside its 12-month incident window.
CoinGecko lists BigONE as established in 2017 and MEXC in 2018, both registered in Seychelles.
BigONE also runs a hack bounty program on HackenProof, according to the program page.
MEXC's security and asset protection measures are set out in full in our separate guide.
For what a reserve report can and cannot prove, see our proof-of-reserves exchanges guide.
Who Should Choose MEXC, and Who Should Choose BigONE?
Choose MEXC if you trade spot often, want 0% on limit orders, or want a higher Trust Score and a documented 500x tier.
Choose BigONE if its fixed futures rates, fiat options or Kazakhstan licence matter more to you, and read its 2025 incident record next to its response.
If neither fits, our 2026 ranking of the best crypto exchanges covers the wider field.
If MEXC fits, send a small test balance first, then place your first entry as a limit order.
Our full MEXC review covers the platform in depth, and our BigONE alternatives comparison sets BigONE against five other venues.
Independent reviews list the United States as excluded for BigONE, and MEXC does not serve US retail users either, so US readers should use a locally authorised platform.

Risk Warning and Regional Notice
Perpetual futures and leverage amplify both gains and losses, and positions can be liquidated for the full margin amount.
At 500x, a move of roughly 0.2% against a position can trigger liquidation, so high tiers suit only experienced traders with strict risk controls.
This article is informational for readers in the United States, the United Kingdom, and Australia, where the platforms discussed may not be available or authorised.
In the EU and EEA, MEXC is not authorized under the Markets in Crypto-Assets Regulation (MiCA).
The Dutch regulator AFM has placed MEXC on its register of non-compliant entities, which ESMA republishes, and readers in those regions should factor this status into any decision.
Nothing here is investment advice, and fees, leverage tiers, and availability change, so confirm current terms on each platform's official pages before trading.
