This tool helps you understand how much you'd save with RDAX.io's low fees versus legitimate exchanges. But remember: extremely low fees often signal serious risks.
RDAX.io claims 0.01% for buyers and 0.02% for sellers, but these fees are unsustainable for legitimate operations. Real exchanges typically charge 0.1%-0.2%.

Important Risk Warning: RDAX.io's fees are 5-20x lower than legitimate exchanges, which is unsustainable for a real business. This is a major red flag. The article highlights that RDAX.io lacks transparency, regulatory oversight, and security measures. Using RDAX.io could result in lost funds with no recourse. We strongly recommend using regulated exchanges like Kraken, Coinbase, or Binance instead.
For context, legitimate exchanges typically charge 0.1% to 0.2% per trade. RDAX.io's fees may seem appealing, but they're often a sign of an unregulated operation that may not be trustworthy.
RDAX.io claims to be a crypto exchange with fees so low they sound like a mistake: 0.01% for buyers, 0.02% for sellers. On top of that, withdrawals are free - no matter if you’re moving Bitcoin, Ethereum, or Monero. That’s not just cheap. It’s unheard of for a centralized exchange in 2025. But here’s the problem: if something looks too good to be true in crypto, it usually is.
What RDAX.io Actually Offers
RDAX.io lists only seven cryptocurrencies: Bitcoin, Ethereum, Litecoin, Monero, Ripple (XRP), EOS, and Tron. That’s it. No Solana, no Cardano, no Dogecoin. No stablecoins like USDT or USDC either. Compare that to Binance, which supports over 1,000 coins, or even smaller exchanges like KuCoin that list 700+. RDAX.io doesn’t just have a small selection - it’s missing nearly every major asset traders use today.
There’s no fiat on-ramp. You can’t deposit USD, EUR, NZD, or any government currency. That means you need to already own crypto to use RDAX.io. You have to buy Bitcoin or Ethereum elsewhere - say, on Coinbase or Kraken - then send it over. That’s not a feature. It’s a barrier. It turns RDAX.io into a niche tool for people who already have crypto and want to trade it cheaply. But if you’re new to crypto, you can’t even get started here.
The Fee Structure Doesn’t Add Up
Most exchanges charge between 0.1% and 0.2% per trade. Even the cheapest platforms like Kraken or NDAX charge 0.16% or more. RDAX.io charges 0.01% for buyers and 0.02% for sellers. That’s 5 to 20 times lower than the industry standard. And they don’t charge withdrawal fees. Not even for Bitcoin, where the average fee is 0.000812 BTC - about $50 at current prices.
How is that possible? Exchanges make money from trading fees and withdrawal charges. They use that revenue to pay for servers, security teams, compliance staff, and customer support. RDAX.io claims to cover all that with near-zero fees and zero withdrawal costs. That’s not sustainable. It’s either a massive subsidy from an unknown source - which no one talks about - or it’s a trap.
Real exchanges don’t give away money. They don’t operate at a loss for years. If RDAX.io were a legitimate business, it would need to be backed by a bank, a VC, or a government entity. None of that is disclosed. No parent company. No headquarters. No team names. No legal jurisdiction.
No One Is Talking About It
Look at any popular crypto exchange - even the obscure ones - and you’ll find Reddit threads, YouTube reviews, Trustpilot ratings, and forum discussions. You’ll see users complaining about slow withdrawals, high fees, or bad UI. That’s normal. It means people are using it.
RDAX.io? Nothing. No Reddit posts. No Trustpilot page. No YouTube reviews. No Twitter chatter. Not even a single mention on CryptoCompare or CoinGecko. It doesn’t appear in any of the top 15 exchange lists from Bitcoin.com, CoinMarketCap, or Cryptowisser’s 2025 rankings. That’s not an oversight. That’s silence.
When legitimate small exchanges launch, they get covered by niche YouTubers and crypto bloggers. Brother Brown reviewed NDAX.io in 2021. CryptoCred talks about every new DEX. But RDAX.io? Crickets. That’s not because it’s too small. It’s because no one trusts it enough to test it.
No Security Info. No Transparency.
Every serious exchange publishes details about security: cold storage, proof-of-reserves, audit reports, insurance policies. Binance has a SAFT. Kraken publishes monthly attestations. Even smaller exchanges like Bitstamp show their reserve proofs.
RDAX.io? Zero. No mention of cold wallets. No audit history. No proof that they hold the crypto users deposit. No insurance for user funds. That’s not just poor transparency - it’s dangerous.
In 2025, the SEC is cracking down on unregistered exchanges. The UK’s FCA has shut down over 200 fake crypto platforms since 2023. Australia’s ASIC has flagged dozens more. If RDAX.io isn’t licensed by any of these agencies - and there’s zero evidence it is - then your funds are completely unprotected.
It’s Not Listed Anywhere
RDAX.io doesn’t show up on CoinGecko. It doesn’t appear on CoinMarketCap. It’s not in Bitcoin.com’s “Top 15 Crypto Exchanges 2025.” It’s not in Slashdot’s list of top exchanges for Radix. It’s not even on the radar of DeFi aggregators like DeFiLlama.
That’s not because it’s too new. It’s because it doesn’t have enough trading volume to be tracked. Real exchanges generate millions in daily volume. Even tiny ones like MEXC or Gate.io report $100M+ in 24-hour volume. RDAX.io? No data. No charts. No order books you can verify. That means either no one trades there - or the numbers are fake.
What You’re Really Getting Into
Let’s be clear: RDAX.io doesn’t look like a scam. It looks like a potential scam. It’s built to look legitimate - low fees, free withdrawals, clean website - but it’s missing every single trust signal that real exchanges provide.
Here’s what’s missing:
- Company registration or legal address
- Team members or leadership names
- Fiat deposit options
- Mobile app or API access
- Staking, lending, or advanced trading tools
- Security audits or proof-of-reserves
- Community presence or user reviews
- Any listing on major crypto data platforms
That’s not a startup. That’s a ghost. And in crypto, ghosts don’t last long.
What Should You Do?
If you’re thinking of using RDAX.io, stop. Don’t send any crypto there. Not even a small test amount. Once it’s gone, it’s gone. There’s no customer service to contact. No legal recourse. No way to recover funds.
Instead, use a real exchange. If you’re in New Zealand, try Independent Reserve or BitMart. If you’re elsewhere, use Kraken, Coinbase, or Binance (where available). They charge more - yes - but they’re regulated, audited, and have millions of users. Your money is safer there.
Low fees are tempting. Free withdrawals are tempting. But in crypto, the cheapest option is rarely the safest. And RDAX.io? It’s the cheapest option - and the riskiest.
Why This Matters in 2025
2025 is the year crypto regulation finally caught up with the industry. The SEC is suing exchanges. The EU is enforcing MiCA. Australia is freezing unlicensed platforms. Even small exchanges now need to prove they’re real.
RDAX.io doesn’t just ignore these rules - it ignores the basics of trust. No transparency. No accountability. No history. That’s not innovation. That’s a warning sign.
If you’re looking for low fees, try dYdX (a decentralized exchange) or Kraken Pro. Both offer competitive rates with full transparency. RDAX.io doesn’t even come close.
Is RDAX.io a scam?
RDAX.io isn’t officially labeled a scam, but it has nearly every red flag of one: no company details, no regulatory license, no security disclosures, no user reviews, and no presence on major crypto data sites. The extremely low fees and free withdrawals are unsustainable for a real business. Until it proves otherwise, treat it as high-risk.
Can I deposit fiat currency on RDAX.io?
No. RDAX.io does not accept USD, EUR, AUD, NZD, or any fiat currency. You must already own cryptocurrency and transfer it from another exchange. This makes it unusable for beginners and limits its usefulness to experienced traders who already have crypto holdings.
Why is RDAX.io not on CoinGecko or CoinMarketCap?
CoinGecko and CoinMarketCap only list exchanges with verifiable trading volume, liquidity, and transparency. RDAX.io has no public trading data, no API access, and no third-party verification. Without these, it doesn’t meet their listing requirements - which is a strong signal that the exchange has little to no real activity.
Are the low fees on RDAX.io real?
The fees are technically real - if you can trade there. But they’re unsustainable. Most exchanges charge 0.1%-0.2% per trade to cover costs. RDAX.io charges 0.01%-0.02% and offers free withdrawals. No legitimate exchange can operate like this long-term without hidden revenue streams or massive funding - neither of which are disclosed.
What should I use instead of RDAX.io?
For New Zealand users, Independent Reserve is regulated and supports NZD deposits. For global users, Kraken, Coinbase, and Binance offer low fees, strong security, and full transparency. If you want decentralized trading, try dYdX or Uniswap. All of these have proven track records, user reviews, and regulatory compliance - unlike RDAX.io.
