BigONE isn’t one of the big names like Binance or Coinbase, but if you’re hunting for obscure altcoins, high-leverage futures, or passive income options beyond staking, it’s still on a lot of traders’ radars. As of October 2025, it lists over 500 cryptocurrencies - way more than most platforms. That’s the main draw. But here’s the catch: BigONE had a $27 million hack in July 2025. And while they promised to cover all losses, trust doesn’t rebuild overnight. So is this exchange still worth your time? Let’s break it down - no fluff, just what matters.
What You Can Trade on BigONE
BigONE doesn’t just offer Bitcoin and Ethereum. It’s packed with tokens most exchanges don’t even bother listing. Think DeFi tokens from smaller chains, memecoins with niche communities, and tokens tied to gaming or metaverse projects you’ve never heard of. If you’re into hunting for the next 10x play, this is one of the few places where you might find it before it blows up on CoinMarketCap.They support spot trading, margin trading (up to 10x), perpetual futures (up to 100x leverage), options, ETFs, and even NFT trading. That’s rare. Most exchanges offer one or two of these. BigONE gives you all of them in one place. The futures trading interface runs on a custom version of TradingView, which is familiar if you’ve used it elsewhere. Charts are clean, indicators load fast, and order types include limit, market, stop-limit, and trailing stop.
For passive income, they offer staking, dual investment (earn fixed returns by locking two assets), copy trading (follow top traders automatically), liquidity mining, and even ETH PoS validator services. You don’t need to run your own node - BigONE handles it. Returns vary, but some staking pools offer 5-12% APY, depending on the asset and lock-up period.
Fees and Deposit/Withdrawal Limits
BigONE’s fee structure is average, not cheap. Spot trading starts at 0.2% for both makers and takers. You can drop that to 0.15% if you hold their native token, BIG. Futures trading is cheaper: 0.02% for makers, 0.06% for takers. That’s competitive with Binance and OKX. No hidden fees on deposits - you can send crypto in for free. But withdrawals? They charge network fees, which are standard. You’ll pay what the blockchain charges - nothing extra from BigONE.Fiat deposits? BigONE supports 13 fiat currencies, including AUD, EUR, GBP, JPY, USD, and CNY. You can buy crypto directly with credit/debit cards, Alipay, WeChat Pay, AdvCash, or Simplex. No minimum deposit. You can start with $1. Withdrawals have limits based on your verification level. Basic users can pull out up to 2 BTC per day. VIPs (tier 2 and above) can go higher - but you need to hit trading volume thresholds to unlock them.
Security: What Happened in July 2025?
This is the elephant in the room. On July 16, 2025, hackers stole $27 million from BigONE’s hot wallets. The breach wasn’t due to a weak password or internal leak. It was a third-party exploit targeting vulnerabilities in their wallet infrastructure. BigONE confirmed that private keys were never compromised - meaning the cold wallets were untouched. Still, $27 million vanished.Here’s what they did after: They immediately paused all withdrawals. They worked with blockchain forensics firm SlowMist to track the stolen funds across Bitcoin, Ethereum, Tron, Solana, and BNB Chain. They publicly shared transaction hashes so the community could follow along. Then, they announced they would fully compensate every affected user - no exceptions. That’s rare. Most exchanges delay or only pay partial amounts.
They resumed deposits and trading within 48 hours. Withdrawals came back online after two weeks, once they upgraded their wallet security, added multi-signature controls, and increased penetration testing frequency. They also boosted their bug bounty program from $50,000 to $500,000 annually. But trust? That’s still fragile. Reddit threads and Twitter replies are full of users saying, “I’ll trade here, but I won’t keep funds here long.”
Customer Support and Usability
BigONE offers 24/7 support via email, live chat, and ticket system. No phone support. That’s normal for non-US exchanges, but it’s a downside if you’re used to instant calls. Response times vary. Some users get replies in under 10 minutes. Others wait 12-24 hours. The chatbot is decent for basic questions, but if you’re stuck on a withdrawal or KYC issue, you’ll need to escalate to a human.The website and mobile apps (iOS and Android) are functional, not beautiful. The layout is cluttered. New users might feel overwhelmed. There’s no guided onboarding. You’re thrown into the trading dashboard with no tutorial. Documentation exists, but it’s written in broken English in places. If you’re tech-savvy, you’ll figure it out. If you’re new? You’ll probably get lost.
Who Should Use BigONE?
BigONE is not for everyone. If you’re in the U.S., you can’t use it. Period. They block all U.S. IPs and require KYC that flags American IDs. So if you’re American, skip it. Look at Kraken or Coinbase.But if you’re outside the U.S. - especially in Southeast Asia, Latin America, or Eastern Europe - and you want access to hundreds of altcoins, high-leverage futures, and passive income tools, BigONE is one of the few platforms that delivers. It’s not the safest. It’s not the easiest. But it’s one of the most diverse.
Use it for short-term trades, not long-term holding. Keep your main portfolio on a more trusted exchange. Use BigONE to speculate on niche tokens or to test high-leverage strategies. Don’t leave funds sitting there for weeks. Withdraw after you’re done trading.
How It Compares to Binance and Kraken
| Feature | BigONE | Binance | Kraken |
|---|---|---|---|
| Cryptocurrencies Listed | 500+ | 350+ | 200+ |
| Max Futures Leverage | 100x | 125x | 50x |
| Fiat Support (Currencies) | 13 | 20+ | 15 |
| US Users Allowed | No | No (except limited services) | Yes |
| Passive Income Options | Staking, copy trading, liquidity mining, ETFs | Staking, savings, futures, NFTs | Staking, earn program |
| Security Incidents (2020-2025) | 1 major ($27M, July 2025) | 1 major ($400M, 2022) | 0 major |
| Mobile App Rating (App Store) | 3.8/5 | 4.7/5 | 4.5/5 |
Binance has more fiat options and better app design. Kraken is the most trusted for security. BigONE wins on altcoin variety and leverage. But it’s the only one with a recent $27M breach. That’s not a small thing.
Final Verdict: Is BigONE Worth It?
BigONE is a high-risk, high-reward exchange. If you’re an experienced trader who knows how to manage leverage, understands the risks of altcoins, and doesn’t mind keeping only small amounts on the platform, it’s a useful tool. You’ll find coins you can’t get anywhere else. You’ll get access to 100x leverage - which is dangerous, but tempting.But if you’re new to crypto, or you want to hold Bitcoin long-term, or you care about trust more than variety - walk away. The July 2025 hack wasn’t the first, and it might not be the last. Even with compensation promises, losing access to your funds for two weeks is stressful. And there’s no guarantee they’ll cover the next breach.
Use BigONE like a casino: bring only what you’re willing to lose. Trade, take profits, withdraw. Don’t store. Don’t over-leverage. Don’t ignore the red flags. It’s not the best exchange. But for certain traders, it’s still one of the few that lets you play the game they want to play.
Is BigONE safe to use in 2025?
BigONE has strong security features like cold storage, two-factor authentication, and proof of reserves. But it suffered a $27 million hack in July 2025, which exposed vulnerabilities in its hot wallet system. While they compensated all affected users and improved security, the incident damaged trust. It’s safer for short-term trading than long-term holding.
Can I use BigONE if I live in the United States?
No. BigONE blocks all U.S. residents and citizens from creating accounts or accessing the platform. Even if you try to bypass the restriction, your KYC will be flagged, and your account will be suspended. U.S. users should use Kraken, Coinbase, or Gemini instead.
What’s the highest leverage available on BigONE?
BigONE offers up to 100x leverage on perpetual futures contracts. This is among the highest in the industry. However, such high leverage is extremely risky and can wipe out your account quickly if the market moves against you. It’s recommended only for experienced traders with strict risk management.
Does BigONE have a mobile app?
Yes. BigONE has official mobile apps for both iOS and Android. The apps support spot trading, futures, staking, and portfolio tracking. However, user reviews rate the apps lower than competitors like Binance or Kraken, citing occasional lag and confusing navigation.
How do I deposit money into BigONE?
You can deposit cryptocurrencies for free. For fiat, you can use credit/debit cards, Alipay, WeChat Pay, AdvCash, or Simplex. The platform supports 13 fiat currencies including AUD, EUR, USD, and JPY. There’s no minimum deposit, so you can start with as little as $1.
What are the trading fees on BigONE?
Spot trading fees start at 0.2% for both makers and takers. You can reduce this to 0.15% by holding BIG tokens. Futures fees are lower: 0.02% for makers and 0.06% for takers. Withdrawal fees vary by cryptocurrency and reflect the network’s standard fees - BigONE doesn’t add extra charges.
Does BigONE offer staking?
Yes. BigONE offers staking for over 100 cryptocurrencies, including ETH, SOL, ADA, and DOT. Returns range from 3% to 12% APY, depending on the asset and lock-up period. They also offer ETH PoS validator services, letting you earn rewards without running your own node.
Why does BigONE have so many altcoins?
BigONE targets traders who want access to obscure and emerging tokens that larger exchanges ignore. They prioritize listing volume and community demand over regulatory compliance for each coin. This makes them a magnet for speculative traders but also increases risk - many listed tokens are low-liquidity or potentially scams.

BigONE is a gamble. Not a platform.

I’ve traded here for over a year. The altcoin list is insane - I found a token no one else had and made 8x in two weeks. But I treat it like a casino. I deposit $200, play, cash out before bed. Never leave more than I’m willing to lose. The UI is clunky, but if you know what you’re doing, it’s a treasure trove. 🤖📈
Benjamin Jackson
I used to be skeptical too - until I saw how fast they handled the hack. Paid everyone. No delays. No excuses. That says more than any security audit. Yeah, the app sucks. Yeah, the interface feels like 2018. But when you need access to a niche DeFi token on Solana at 3 AM, BigONE’s the only one that shows up. I’m not staying rich here. I’m just trading smart.
Leo Lanham
LOL you people act like this exchange is some kind of villain. Binance stole $400M and you still use it. Kraken’s fine for grandma’s portfolio but it’s got less coins than my local gas station has snacks. BigONE gives you the wild west - you want safety? Go to a bank. You want crypto? Deal with the chaos. Stop crying about a $27M hit. That’s less than what Elon lost in a weekend.
Whitney Fleras
For new traders: if you’re thinking of using this, start with $10. Just test the waters. Don’t go all in. Learn how the interface works. Watch how withdrawals take 12–24 hours. Then decide if it’s worth the hassle. It’s not evil - it’s just not for beginners.

I can't believe people still entertain this exchange. A $27 million hack is not a feature. It's a warning label. If you're not American, you're either naive or desperate. The fact that you're even considering this over Kraken or Coinbase says more about your risk tolerance than your financial literacy.
Brian Webb
I live in Canada and use BigONE for altcoin exposure only. I keep 95% of my portfolio on Coinbase. The rest? Small bets. I like that they have copy trading - I followed a guy who hit a 14x on some obscure NFT token. Got my profit, withdrew. Done. The app’s ugly, but it works. I don’t need glitter. I need access.
Matthew Gonzalez
The real question isn't whether it's safe. It's whether you're smart enough to use it. I’ve lost money here. I’ve made money here. The key is treating it like a tool, not a bank. Withdraw after every trade. Don’t sleep with your coins here. And never, ever use max leverage unless you’ve got a death wish. It’s not the exchange that’s dangerous - it’s the people who treat it like a lottery.
Michelle Stockman
Oh wow, someone actually wrote a 2000-word essay on why BigONE is the crypto equivalent of a broken ATM that still spits out cash sometimes. Congrats. You’ve just convinced me to never touch it. Also, 100x leverage? That’s not trading. That’s gambling with a spreadsheet.
Colin Byrne
Let’s be honest - the entire crypto industry is built on trust erosion. Binance’s $400M hack was covered up for months. Kraken’s never had a breach because they don’t list anything interesting. BigONE had a hack, admitted it, compensated everyone, and upgraded. That’s more integrity than 90% of exchanges show. The fact that you’re still scared means you don’t understand risk. You think security is about zero breaches? No. Security is about transparency after failure. BigONE passed that test.
Alexis Rivera
I’m from Mexico and I use BigONE because it’s one of the few platforms that accepts Mexican pesos via OXXO. I’ve had no issues. The altcoins are wild - I traded a token tied to a Mexican indie game last month. It’s not perfect. But it’s functional. And for people outside the U.S. and EU, it’s one of the only real options. Don’t hate the tool because your wallet’s too small to use it properly.
Eric von Stackelberg
The July 2025 hack wasn’t a random exploit. It was an inside job. The blockchain forensics were too clean. SlowMist was paid to spin the narrative. They didn’t lose $27M - they moved it. The compensation? A PR stunt to lure more funds in. Cold wallets untouched? That’s what they want you to believe. The real cold wallets? Still empty. This isn’t an exchange. It’s a Ponzi with a TradingView interface.
John Doe
I used to be a BigONE user. Then I lost my entire $15k position in one 30-second flash crash. The 100x leverage didn’t just wipe me out - it wiped out my mental health. I had panic attacks for weeks. I still check their site every day. Hoping they’ll fix it. They won’t. They don’t care. This isn’t trading. It’s emotional abuse wrapped in a whitepaper.
Ryan Inouye
Americans are so soft. You want safety? Go live in a bubble. BigONE is for people who actually want to win. If you can’t handle a little risk, go back to your 401k and stop pretending you’re a crypto investor. This isn’t a bank. It’s a battlefield. And if you’re not ready to fight, don’t bring your teddy bear to the arena.
Rob Ashton
I’ve been mentoring new traders for years. I always tell them: if you’re drawn to BigONE because of the 100x leverage or the obscure tokens, you’re not ready. But if you’re drawn to it because you want to learn how to manage risk in a high-stakes environment - then it’s one of the best classrooms out there. Just don’t stay long. Trade. Learn. Withdraw. Repeat.
