2025/11 Crypto Archive: Scams, Airdrops, and Blockchain Tech Explained

When you’re navigating crypto in late 2025, you’re not just chasing gains—you’re filtering out lies. The crypto airdrop, a free token distribution meant to grow a project’s community. Also known as token giveaway, it’s become a magnet for fraudsters pretending to be legitimate teams. In November 2025, we called out fake airdrops like APAD, Cannumo, and StarSharks that never existed—and confirmed which ones, like PSWAP and CORA, had real but stalled launches. Meanwhile, blockchain identity, a system letting you control your personal data without handing it to corporations. Also known as self-sovereign identity, it’s the quiet revolution behind faster logins, safer KYC, and privacy that actually works. These aren’t buzzwords—they’re tools that separate the trustworthy from the trash.

And then there’s the crypto exchange, a platform where you buy, sell, or trade digital assets. Also known as cryptocurrency trading platform, it’s where most people get burned—not because the tech is broken, but because they picked the wrong one. In November, we reviewed real platforms like CoinZoom and BICC Exchange, but also exposed outright scams like GJ Crypto and Crypcore that had zero users, zero licenses, and zero history. We dug into niche DEXes like Fraxswap and DerpDEX to show who they’re really for: not casual traders, but people who know exactly what they’re doing. And we didn’t skip the basics: hash algorithms, the mathematical engines that secure blockchains like Bitcoin and Ethereum. Also known as cryptographic hash functions, they determine how mining works, how fast transactions settle, and why some coins are more decentralized than others. SHA-256, Keccak, BLAKE2—these aren’t just acronyms. They’re the reason your Bitcoin stays yours.

What you’ll find below isn’t a random list. It’s a map of what actually happened in crypto during November 2025: the airdrops that vanished, the exchanges that betrayed trust, the tech that kept working, and the scams that got exposed. No fluff. No hype. Just facts, warnings, and straight talk about what you need to know before you click, trade, or invest.
