The concessions are real too: BigONE's futures schedule of 0.02% maker and 0.06% taker is level with the majors, and its July 2025 security incident sits next to a full-compensation pledge and same-day service restoration.

Bybit, OKX, Bitget, KuCoin, and Gate complete the field.

Key Takeaways

MEXC is our top pick among BigONE alternatives: 0% maker spot with a 0.05% taker, 0.02% taker on BTCUSDT's Special Rate, a 9/10 trust score, and a public PoR page (August 11, 2026).
BigONE charges 0.2% for spot makers and takers at its Bronze base tier, with futures fixed at 0.02% maker and 0.06% taker across tiers, per multiple trackers.
In July 2025, BigONE lost about 27 million dollars in a hot-wallet incident and said all user losses would be covered in full, with deposits and trading expected to resume within hours, per CoinDesk.
CoinGecko scores BigONE 5/10 with a reserve-data badge and about 8,000 BTC in same-day volume (August 11, 2026).
Its futures schedule is level with the majors, which is a real concession this comparison does not take back.
Standard MEXC contracts top out at 0.040% taker on the official schedule, while API orders bill at 0.08%, so the fee edge holds on spot and manual futures.

Why MEXC Is Our Top BigONE Alternative

A BigONE trader weighing a move usually wants three things: cheaper spot execution, a stronger trust score, and a security record without an incident to weigh.

On spot, MEXC charges 0% maker and 0.05% taker against BigONE's 0.2% on both sides at Bronze tier, a quarter of the cost for takers and the whole fee for makers.

On the score, MEXC holds a 9/10 on CoinGecko with a public proof-of-reserves page, against BigONE's 5/10 with a reserve-data badge.

On the record, MEXC has operated since 2018 and has not disclosed a comparable hot-wallet loss, while BigONE's July 2025 loss sits on the record next to its compensation commitment, and this article lays both out below rather than trading on either.

Around that sit more than 900 perpetual markets (Coinspeaker, December 2025) and a 500x BTCUSDT and ETHUSDT tier documented in a public announcement, against BigONE's published 100x ceiling.

Put numbers on the spot side with 5,000 USDT of monthly volume.

A year of taker orders costs about 120 USDT on BigONE's Bronze tier and about 30 USDT on MEXC, with the 0.10% platforms at 60 USDT.

The live schedule, including which contracts carry the Special Rate tag, sits on the fee page.

The caveats run in both directions.

On the official schedule, standard non-tagged contracts top out at 0.010% maker and 0.040% taker, but API futures orders bill at a separate 0.06% maker and 0.08% taker as of June 1, 2026, which matters for bot traders.

The 500x tier is unavailable in ten regions listed in MEXC's own announcement, including the UK and Canada, and copy trading does not support it.

BigONE, for its part, prices futures level with the majors, takes fiat in thirteen currencies with card support per independent reviews, and honoured a full-compensation pledge process after its 2025 incident, which is more than some venues have managed.

The July 2025 BigONE Hack

On July 16, 2025, BigONE confirmed a loss of about 27 million dollars from its hot wallets, per CoinDesk.

SlowMist attributed the breach to a compromise of the production network that altered account and risk-control server logic rather than to stolen private keys, in a July 16, 2025 alert.

BigONE stated that all user losses would be fully covered from internal reserves and external liquidity, said trading and deposits would resume within hours, and delayed withdrawals until security hardening was complete.

One year on, CoinGecko lists BigONE at 5/10 with a reserve-data badge and tracked volume, which is the objective follow-up a reader can check today.

The incident record and the response record belong side by side, and both are part of vetting any venue.

BigONE Alternatives Compared: Fees, Leverage, and Trust Scores

Binance, one of the three largest exchanges by volume (CoinGecko, August 11, 2026), is left out of this table because its published rates could not be independently confirmed at the time of writing.

Platform	Spot fees (base maker / taker)	Futures fees (base maker / taker)	Max leverage (published)	Trust score / reserves (CoinGecko, Aug 11, 2026)
BigONE	0.2% / 0.2% (Bronze tier; reduced at higher tiers)	0.02% / 0.06% (fixed across tiers)	Up to 100x	5/10; tracked
MEXC	0% / 0.05%	0%–0.010% / 0%–0.040% (BTCUSDT Special Rate: 0% / 0.02%)	Up to 500x (BTCUSDT, ETHUSDT; official announcement)	9/10; tracked, public PoR page
Bybit	0.1% / 0.1%	0.02% / 0.055%	Varies by pair	9/10; tracked
OKX	0.08% / 0.10%	0.02% / 0.05%	Varies by pair	10/10; tracked
Bitget	0.1% / 0.1%	0.02% / 0.06%	Varies by pair	10/10; tracked
KuCoin	0.1% / 0.1% (Class A pairs)	0.02% / 0.06%	Varies by pair	9/10; tracked
Gate	0.10%–0.20% (verify in account)	0.015–0.02% / 0.05%	Up to 100x	10/10; tracked

Data verified as of August 11, 2026 against each platform's official fee schedule or help center where accessible; BigONE rates converge across Bitdegree, Cryptowisser, LiquidityFinder, and other trackers and are pending direct confirmation, OKX figures were cross-checked with independent fee trackers, and Gate's published spot rates diverged after its April 9, 2026 restructure. Trust scores and reserve status per CoinGecko's exchange ranking the same day. MEXC futures figures follow the official fee page as of August 2026: standard USDT-M contracts list 0%–0.010% maker and 0%–0.040% taker, with Special Rate levels set per pair (BTCUSDT 0% / 0.02%, ETHUSDT 0% / 0.01%). MEXC API futures orders follow a separate schedule of 0.06% maker and 0.08% taker, effective June 1, 2026, per the official MEXC fee page.

Is BigONE Safe? The 3-Point Trust Check, Applied

Smaller exchanges are not automatically unsafe, and big names are not automatically safe; the same three checks work on any venue.

Trust score: look up the exchange on CoinGecko and read the rating against its published methodology.
Reserves: check for a reserve-data badge and an official proof-of-reserves page with a recent date.
Disclosure: confirm who operates the platform, from where, and since when, using its legal pages and independent reviews.

Applied to BigONE on August 11, 2026, the checklist reads differently from most small venues, because here there is an incident record to weigh.

The score check is a caution: 5/10, in the lower half of this comparison.

The reserve check carries the history: a reserve-data badge today, and a 2025 stress test in which the platform pledged full compensation and restored services the same day, per mainstream reporting.

Disclosure is mixed and moving: a 2017 start registered in Seychelles with thin structure detail per Tradingfinder, while a June 2026 industry profile cites a Kazakhstan AFSA licence; AFSA's own public register is the place to confirm the current scope.

The United States is excluded, and fiat rails run through cards and thirteen currencies per independent reviews.

The reading: judge the incident and the response together, verify terms in-app, and size positions to the open questions rather than to the headlines.

The Other Five BigONE Alternatives, and What Each One Wins On

Bybit

Bybit halves BigONE's spot rate at 0.1% and posts a 0.055% futures taker, backed by some of the deepest derivatives books in the market.

Spot at 0.1% both sides, half of BigONE's Bronze rate.

Where BigONE Falls Short, and What It Still Does Well

The verifiable strengths deserve a fair statement before the shortfalls.

A futures schedule of 0.02% maker and 0.06% taker, level with the majors and fixed across tiers.
A public commitment to cover user losses in full after the July 2025 incident, per CoinDesk.
A reserve-data badge on CoinGecko with about 8,000 BTC in same-day volume.
Fiat support in thirteen currencies with card payments, per independent reviews.
A Kazakhstan AFSA licence covering exchange, clearing, and custody, per a June 2026 profile.

The shortfalls are just as concrete.

The Bronze-tier 0.2% spot rate applies to makers and takers alike, tied for the highest standard rate in this table.

The 5/10 trust score sits in the lower half of this comparison, and the incident record is part of any honest read.

Structure detail is thin per Tradingfinder, the published leverage ceiling stops at 100x, and the United States is excluded.

How to Move Funds Off BigONE in Three Steps

Close or roll open positions first, since open perpetuals cannot transfer between venues.
Match the withdrawal network to the receiving deposit network, with any memo or tag copied exactly.
Send a small test amount, then the remaining balance once it lands.

Check minimum withdrawal amounts for the asset and network before sending.

Confirm any memo or tag requirement on the receiving side.
Withdraw a test amount before the full balance.
Keep both transaction hashes for your records.

Which Platform Fits Which Trader

Choose MEXC if spot costs, a 9/10 score, and a record without an incident to weigh decide it for you.

Choose OKX or Gate to undercut BigONE's futures taker under 10/10 scores, Bybit for depth, Bitget for copy trading, and KuCoin for altcoin range.

Stay on BigONE if its futures pricing and fiat rails cover your needs, and read the incident record next to the response record before sizing positions.

Bot traders should compare API schedules directly, because MEXC's 0.08% API taker changes that math.

Risk Warning and Regional Notice

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.
