ONUS Pro Crypto Exchange Review: Fees, Features, and Real User Risks in 2025

When you’re looking for a crypto exchange that actually works for people in Southeast Asia, ONUS Pro stands out - but not because it’s perfect. It’s built for traders in Vietnam, Thailand, and Indonesia who want to trade crypto without jumping through hoops. It connects directly to local banks, supports VNDC, offers crazy high yields on stablecoins, and even lets you trade futures with 125x leverage. But behind the shiny features, there are real problems - especially when it comes to customer service and promised bonuses.

What ONUS Pro Actually Offers

ONUS Pro isn’t just another crypto exchange. It’s a full-stack platform designed for the Southeast Asian market. You can trade over 600 cryptocurrencies on spot markets and more than 200 futures contracts. The platform supports major blockchains like Bitcoin, Ethereum, BSC, TRON, Solana, and Ton Network. That means you can deposit and withdraw using almost any wallet you already own.

What makes it different? The DeFi wallet. You don’t need separate wallets for Ethereum, Solana, or Ton. ONUS Pro bundles them all into one interface. You can store, send, receive, buy, and sell coins - all inside the app. It’s like having a crypto bank account that works across networks without switching apps.

Trading Fees That Actually Save You Money

If you trade often, fees matter. ONUS Pro charges 0.1% for spot trades - standard for the industry. But for futures? It drops to 0.02%-0.04%. That’s lower than Binance, KuCoin, and most regional rivals. For active traders, that adds up fast. Over 100 trades a month? You could save hundreds in fees compared to other platforms.

The minimum order size is just $10. That’s low enough for beginners to test the waters. No need to risk thousands just to get started. And deposits? You can start with as little as 1,000 VNDC on TRON, or 20,000-200,000 VNDC on other chains. That’s roughly $0.40 to $8 USD - accessible even if you’re not wealthy.

High-Yield Savings That Actually Pay

Most exchanges offer 3-5% APY on stablecoins. ONUS Pro offers up to 12.8% on VNDC and USDT. On Bitcoin and Ethereum, you can earn up to 12% annually. That’s not a gimmick - it’s real. The platform locks your funds in DeFi lending pools, and the returns are distributed weekly.

You get two options: flexible savings (withdraw anytime) or term savings (lock for 7, 30, or 90 days for higher rates). If you’re holding USDT and don’t plan to trade it soon, putting it in ONUS Pro’s savings account is one of the best ways to make it work for you. No other exchange in Southeast Asia offers this kind of yield on local currency assets.

Bank Integration: The Real Secret Weapon

ONUS Pro doesn’t just talk about fiat on-ramps - it actually built them. The platform has direct partnerships with over 30 Vietnamese banks, including Vietcombank, BIDV, Techcombank, and ACB. You can deposit Vietnamese dong directly from your bank account and convert it to USDT or VNDC in minutes.

This is huge. Most exchanges force you to use third-party payment processors with high fees and long delays. ONUS Pro cuts out the middleman. If you live in Vietnam, this is the easiest way to buy crypto without dealing with P2P scams or risky exchanges.

The Beta Spot Trading Feature - What You Need to Know

As of October 2025, ONUS Pro launched a beta version of spot trading in its mobile app (version 5.8.1). It’s only available to VIP Level 3 users and business partners. The interface is clean: you can place market and limit orders, just like on Binance or Coinbase.

But here’s the catch: your spot wallet balance is separate from your main wallet. You can’t withdraw funds from the beta spot wallet back to your main account. That’s a red flag - it’s a test. If you deposit $1,000 into the spot wallet, you can trade it, but you can’t pull it out. That’s not how a real exchange works.

Expect the full launch to happen in early 2026. Until then, treat the beta as a demo. Don’t risk money you can’t afford to lose.

Ownership Change: Vemanti Group Takes Full Control

On October 1, 2025, Vemanti Group, Inc. (OTC: VMNT) bought the remaining 49% of ONUS Pro’s parent company, XPLOR Technology. This means Vemanti now owns 100% of the platform. The original co-founder, Chien Tran, is joining Vemanti’s board.

This isn’t just a corporate reshuffle. It’s a signal that ONUS Pro is getting serious about scaling. Vemanti has U.S. backing and access to capital. That could mean faster development, better security, and more global features. But it could also mean a shift away from its Southeast Asian roots. Will they keep the low fees? Will they keep the high yields? No one knows yet.

Big Problems: Customer Service and Promotional Scams

Here’s the dark side. Google Play Store reviews are full of complaints. One user says they’ve been waiting two years for a $10 sign-up bonus that was never paid. Others report messages going unanswered for weeks. One reviewer called it “very scammy” and warned others to “be mindful.”

The app still has a 4.4-star rating - but that’s misleading. Most positive reviews come from users who just deposit, earn high APY, and leave. The angry ones? They stay. They’re the ones fighting for their money.

If you’re planning to trade big or rely on bonuses, tread carefully. There’s no guarantee they’ll honor promises. And if something goes wrong, you’re not talking to a live agent in the U.S. or Europe. You’re talking to a support team in Vietnam - and they’re overwhelmed.

How It Compares to KuCoin and Other Regional Exchanges

Let’s be clear: ONUS Pro isn’t better than KuCoin. KuCoin has higher liquidity, more global users, and a 4.5-star rating. But KuCoin doesn’t support VNDC. It doesn’t connect to Vietnamese banks. If you’re in Hanoi or Ho Chi Minh City, ONUS Pro is the only exchange that makes sense.

Here’s the comparison:

If you’re in Southeast Asia and want to earn high yields on stablecoins, ONUS Pro wins. If you want fast, reliable support and global liquidity, go with KuCoin. But if you need to deposit Vietnamese dong directly and want to trade futures with high leverage? ONUS Pro is your only real option.

Who Should Use ONUS Pro?

You should use ONUS Pro if:

• You live in Vietnam or another Southeast Asian country and want to deposit local currency
• You’re looking for high APY on USDT or VNDC - 12%+ is rare elsewhere
• You trade futures and want 125x leverage
• You’re okay with slow customer service and risk of unfulfilled bonuses

You should avoid ONUS Pro if:

• You’ve been burned by crypto platforms before
• You need instant customer support
• You’re planning to deposit large sums and rely on bonus offers
• You want a platform with a proven global reputation

The platform is great for small traders and yield hunters. It’s risky for anyone who needs reliability.

Final Verdict: Worth It?

ONUS Pro is not a safe, boring exchange. It’s bold, fast, and risky. It gives you access to features no other regional platform does - especially the bank links and high-yield savings. But it also has a history of broken promises and ignored complaints.

If you’re comfortable with risk and want to maximize returns in Southeast Asia, ONUS Pro is worth trying - but only with money you can afford to lose. Don’t deposit your life savings. Don’t trust the bonus promises. Use it like a tool, not a bank.

With Vemanti Group now in full control, things might improve. Or they might change in ways that hurt users. Watch closely. The next six months will tell us if this is the future of Southeast Asian crypto - or just another flash in the pan.
