Centralized Crypto Exchange: What It Is, How It Works, and Which Ones to Avoid

When you buy Bitcoin or trade Ethereum, you’re probably using a centralized crypto exchange, a platform owned and operated by a company that holds your crypto and manages trades on your behalf. Also known as CEX, it’s the most common way beginners enter crypto—but it’s also where most scams and hacks happen. Unlike decentralized exchanges, where you control your keys, a centralized exchange acts like a bank: you deposit your crypto, they store it, and they execute your trades. That convenience comes with big risks—if the exchange gets hacked, goes bankrupt, or gets shut down by regulators, your money could vanish.

That’s why knowing the difference between a legit exchange and a fake one matters. Bitfinex, a long-standing platform with deep liquidity and advanced tools for pros, offers features like margin trading and API access, but has terrible customer support and no insurance. On the other hand, BitxEX, a platform flagged by experts as a scam, has fake traffic, no regulation, and users report being locked out of their accounts. Then there’s DubiEx, a platform claiming zero fees but offering zero transparency. No reviews. No security details. Just promises. These aren’t just different exchanges—they’re different levels of risk.

Regulation plays a huge role too. In Nigeria, only two exchanges are legally allowed to operate. In Hong Kong, platforms like HashKey must follow strict rules. But in places with no oversight, anyone can set up a fake exchange and disappear with your funds. That’s why you can’t just pick the one with the prettiest website. You need to know who runs it, where it’s based, and whether it’s been audited. The posts below cover real cases: from exchanges that got banned in China to ones that stole millions. Some are warnings. Others are guides. All of them are real.

What you’ll find here isn’t theory. It’s what happened to real people using real platforms. Whether you’re looking for the safest place to trade, trying to avoid a scam, or just wondering why your favorite exchange suddenly vanished—this collection has the answers you won’t find on YouTube ads or Telegram groups.
