Crypto Airdrops and Exchanges in November 2025: What Worked, What Failed, and What’s Still Active
When you hear crypto airdrop, a free token distribution meant to grow a project’s user base. Also known as token giveaway, it’s often the first thing new users look for—but most never deliver on their promises. In November 2025, the landscape was clearer than ever: the hype-driven airdrops from 2021 were long gone, and what remained were either active trading incentives or outright scams. Projects like O3 Swap and WagyuSwap had ended their airdrops years ago, yet people still searched for them. Meanwhile, Sphynx Network and Bullieverse were the only ones still teasing real, verifiable opportunities—with no official dates, but enough activity to make tracking them worth your time.
crypto exchange, a platform where you buy, sell, or trade digital assets. Also known as cryptocurrency trading platform, it’s the gateway to the market—but not all gateways are safe. This month’s posts exposed exchanges that never worked (Paycml, 1BCH.com), ones that shut down (OPNX, FreiExchange), and a few that still had users despite flaws (CoinFalcon, Swych). Most had one thing in common: low liquidity, no regulation, and hidden fees. Meanwhile, Swiss banks stood out as the only trusted option for holding crypto at scale, thanks to strict custody laws and segregation rules. And while decentralized exchanges like Bancor and Core Dao Swap promised zero fees, they had zero users. The truth? If no one’s trading on it, it doesn’t matter how clever the tech is.
DeFi, a system of financial services built on blockchain without banks. Also known as decentralized finance, it’s where airdrops and exchanges often overlap. Tokens like WQUIL, HQ, and ML tried to bring DeFi to new chains or layers, but most failed because they solved problems no one had. Mintlayer, for example, offered native Bitcoin DeFi without wrapping—something real, but still ignored by most traders. And then there were the meme coins: NEVER, CNC, KABOSU, MOG CAT—each with zero utility, no team, and prices that crashed 99%. They weren’t investments. They were social experiments. Meanwhile, staking became riskier than ever. Slashing penalties wiped out rewards overnight for users who didn’t monitor their validators. And if you lived in Russia or China, your options were even tighter: crypto ownership was legal only for the rich, and payments were outright banned.
What you’ll find below isn’t a list of winners. It’s a record of what happened when the noise faded. You’ll see real breakdowns of failed exchanges, dead airdrops, and regulations that changed everything. No fluff. No hype. Just what worked, what didn’t, and why.
OPNX was a crypto exchange that tried to trade bankruptcy claims from failed firms like FTX and Celsius. It launched in 2023, saw almost no trading volume, and shut down in February 2024. Its founders' history and lack of demand doomed it from the start.
