Trading Fees: 0.3% - 0.5%

If you're in Brazil and looking for a crypto exchange that actually speaks your language - literally and figuratively - Coinext might be worth your attention. Launched in 2017, it’s one of the older platforms in Brazil’s crypto scene, built from the ground up for local users. Unlike global giants that force you to navigate English interfaces and deal with international banking hurdles, Coinext is designed for Brazilians: everything is in Portuguese, payments connect to local banks, and compliance follows Brazil’s financial rules.

What You Can Do on Coinext

Coinext lets you buy, sell, store, and send Bitcoin, Ethereum, and a handful of other major cryptocurrencies. You can trade between Coinext users or move funds in and out of external wallets. The platform supports multiple blockchain networks, so you’re not stuck paying high fees just because the default network is congested. You can pick the cheapest or fastest option based on your needs.

The mobile app and website work smoothly. There’s no lag during peak trading hours, and the interface is clean - no cluttered dashboards or confusing menus. If you’ve used a Brazilian fintech app like Nubank or PicPay, the experience feels familiar. You tap, confirm, and your trade goes through. No need to be a tech expert.

Security and Compliance

Coinext doesn’t cut corners on security. All accounts require full verification - ID, proof of address, and facial recognition. That’s not just bureaucracy; it’s how they comply with Brazil’s anti-money laundering laws. Without this step, you can’t send or withdraw crypto. That’s a good thing. It means your account is locked down, and the exchange is playing by the rules.

They claim to use regulated custody services from a global provider, which means your coins aren’t sitting in a hot wallet somewhere vulnerable. Instead, most assets are stored offline, with encryption and multi-signature access controls. While they don’t publish audit reports or third-party security certifications, their compliance track record since 2017 suggests they’ve learned from early mistakes in the industry.

Referral Program That Actually Pays

One of Coinext’s standout features is its referral program. If you invite a friend and they complete R$100 in trades, you both get R$25 in Bitcoin. That’s real value - not points or coupons. And it doesn’t stop there. You also earn a percentage of your referral’s future trading fees. So if they trade regularly, you keep earning passively.

This isn’t a gimmick. It’s a real incentive structure that’s worked for them since day one. In a market where most exchanges offer vague “bonuses,” Coinext gives you actual Bitcoin. That kind of transparency builds trust.

Education for New Users

If you’re new to crypto, Coinext doesn’t throw you into the deep end. They’ve built a library of hundreds of articles, videos, and guides - all in Portuguese. Topics range from “What is Bitcoin?” to “How to read candlestick charts.” There’s no fluff. Each piece answers a specific question you’re likely to have.

You won’t find advanced algorithmic trading strategies here, and that’s fine. Coinext targets retail investors, not hedge funds. Their educational content is practical, not theoretical. If you’re trying to understand how to buy your first Bitcoin without getting scammed, this is exactly the kind of help you need.

What’s Missing?

Here’s the reality: Coinext isn’t trying to be Binance or Kraken. It doesn’t offer futures trading, margin, staking, or APIs for bots. If you’re looking to trade derivatives or automate your strategy, you’ll need another platform. Coinext keeps things simple: buy, sell, hold, send.

They also don’t list hundreds of altcoins. You’ll find the top 10-15 cryptocurrencies - the ones most people actually use. No obscure tokens with zero volume. That’s a plus if you want to avoid gambling on low-liquidity coins. But if you’re chasing the next memecoin, you’ll be disappointed.

Fee structures aren’t published in detail. Based on user reports, trading fees appear to be around 0.3% to 0.5%, which is standard for regional exchanges. Withdrawal fees vary by coin and network, but they’re transparent - you see the cost before confirming. No hidden charges.

Customer support is available via chat and email, but response times aren’t instant. Most users report answers within 24-48 hours. That’s slower than some global platforms, but acceptable for a mid-sized exchange focused on Brazil’s market.

How Coinext Compares to Other Brazilian Exchanges

Coinext sits between the big players like Mercado Bitcoin and smaller niche platforms. Mercado Bitcoin has higher liquidity and more trading pairs, but its interface feels outdated. Foxbit offers more advanced tools, but the learning curve is steep. Coinext strikes a balance: easy to use, reliable, and built for everyday users.

It doesn’t have the brand recognition of Mercado Bitcoin, but it’s growing steadily. With $5.4 million in annual revenue, it’s not a startup anymore - it’s a functioning business with a loyal user base. That kind of stability matters when you’re storing your money on a platform.

Who Is Coinext For?

Coinext is perfect if you:

Live in Brazil and want to trade crypto in Portuguese
Prefer a simple, no-nonsense interface over flashy features
Want to earn Bitcoin just by inviting friends
Need a secure place to hold Bitcoin without overcomplicating things
Are new to crypto and need clear, local-language education

It’s not for you if you:

Want to trade futures or leverage
Need API access for automated trading
Are looking for 200+ altcoins
Expect 24/7 live phone support

Final Verdict

Coinext isn’t the biggest crypto exchange in Brazil, but it’s one of the most thoughtful. It understands its audience. It doesn’t try to copy global platforms. It builds what local users actually need: simplicity, security, and real rewards.

The fact that it’s been around since 2017 - through bull runs, crashes, and regulatory shifts - says a lot. It’s not a flash in the pan. It’s a platform that’s earned its place by sticking to the basics and doing them well.

If you’re a Brazilian investor looking for a trustworthy, straightforward way to get into crypto, Coinext deserves a spot on your shortlist. Sign up, complete verification, and try the referral program. You might just earn your first Bitcoin without spending a cent.

Is Coinext safe to use in Brazil?

Yes, Coinext is safe for Brazilian users. It requires mandatory KYC/AML verification, uses regulated custody services, and encrypts all data. The platform has operated since 2017 without any public security breaches. It follows Brazil’s financial regulations, making it one of the more compliant regional exchanges.

Can I trade altcoins on Coinext?

You can trade the most popular cryptocurrencies like Bitcoin, Ethereum, Binance Coin, Cardano, and major stablecoins like USDT and USDC. Coinext doesn’t list hundreds of obscure tokens. It focuses on assets with real trading volume and demand in Brazil, reducing risk for users.

Does Coinext have a mobile app?

Yes, Coinext has a free mobile app for Android and iOS. The app mirrors the website’s functionality, allowing you to trade, check balances, and send crypto on the go. It’s optimized for Brazilian networks and works reliably even on slower connections.

How do I withdraw money from Coinext?

You can withdraw cryptocurrency to any external wallet. There’s no direct fiat withdrawal to Brazilian bank accounts. To turn crypto into reais, you’ll need to send your coins to another exchange like Mercado Bitcoin that supports PIX or bank transfers, or use a P2P service. This is common for many Brazilian crypto platforms.

Are there fees for trading on Coinext?

Trading fees are typically between 0.3% and 0.5% per transaction. Withdrawal fees vary by cryptocurrency and network - for example, Bitcoin withdrawals may cost R$5-R$15 depending on blockchain congestion. All fees are shown clearly before you confirm any action. There are no hidden charges.

Does Coinext offer staking or passive income?

No, Coinext does not currently offer staking, lending, or interest-bearing accounts. The platform is focused on trading and secure storage. If you want to earn passive income from crypto, you’ll need to use a different service.

Is Coinext better than Mercado Bitcoin?

It depends on your needs. Mercado Bitcoin has higher liquidity and more trading pairs, making it better for large trades. Coinext has a cleaner interface, better education for beginners, and a more generous referral program. If you’re new or prefer simplicity, Coinext wins. If you trade large volumes daily, Mercado Bitcoin may be more efficient.

OH MY GOD. I just signed up after reading this and I’m already crying. Like… I’ve been waiting for a crypto platform that doesn’t make me feel like I need a PhD in blockchain just to send $20. The fact that it’s in PORTUGUESE?!!?? I have a Brazilian cousin who’s been begging me to help her get into crypto and now I can actually point her somewhere that doesn’t make her feel like an idiot. This is the kind of platform that changes lives. I’m telling my whole family. I’m telling my dog. I’m telling my neighbor’s cat. 🥹💎

Really appreciate how this review focuses on actual user needs instead of hype. The emphasis on KYC compliance and cold storage is refreshing-so many platforms pretend security is optional. And the educational content in Portuguese? That’s not just nice, it’s necessary. Crypto adoption in Brazil isn’t about speculation-it’s about financial inclusion. Coinext gets that.

Look, I don’t care if it’s ‘built for Brazilians.’ This is just another ‘local’ platform trying to act like it’s special because it speaks Portuguese. Meanwhile, Binance offers 50 languages, 200+ coins, and APIs. This is like bringing a spoon to a gunfight. And no staking? Come on. If you’re not earning yield, you’re losing. This isn’t innovation-it’s nostalgia.

It’s cute how they think simplicity is a virtue. I mean… you’re telling me I can’t trade perpetuals or use leverage? How… quaint. And ‘no obscure tokens’? That’s not safety, that’s censorship. This isn’t a platform-it’s a cozy blanket for people who are scared of the market. I feel sorry for them.
