Crypto Myths and Realities in November 2025: Rollups, Airdrops, and Exchange Risks

When it comes to crypto myths, false beliefs about blockchain technology that mislead investors and users. Also known as crypto scams or misconceptions, these myths drive poor decisions, wasted money, and broken trust in the space. In November 2025, the most dangerous myths weren’t about Bitcoin going to $1 million—they were about fake airdrops, phantom exchanges, and scaling solutions that promised the world but delivered nothing.

Take rollups, a blockchain scaling technique that batches transactions off-chain to reduce fees and increase speed. Also known as ZK-rollups and optimistic rollups, they’re the reason DeFi and gaming are finally becoming affordable. But not every project calling itself a "rollup" actually uses one. Many are just rebranded tokens with zero technical innovation. Real rollups like those used by Arbitrum and zkSync cut fees by 90%—while fake ones just charge you more for nothing. Then there’s the airdrop, a free distribution of crypto tokens to attract users. Also known as token giveaways, they used to be a way to bootstrap communities. Now, 8 out of 10 "airdrops" listed on CoinMarketCap are scams. TacoCat, ZeroHybrid, PNDR—they all promised free tokens but had no team, no code, and no future. The only ones worth your time are those tied to real protocols like Coreum or Hop Protocol, which actually move value. And don’t get fooled by exchanges. Purple Bridge, BTB.io, INRTOKEN—these names sound legit, but they have no users, no audits, no support. Meanwhile, real players like Swiss banks and OKX offer regulated custody, staking, and trading under strict oversight. You don’t need a new exchange. You need a secure one.

Behind every fake token is a deeper issue: decentralized identity, a system that lets you own your online data without relying on corporations. Also known as DIDs and verifiable credentials, it’s the missing piece that could stop scams before they start. Imagine being able to prove you’re not a bot before claiming an airdrop—or verifying an exchange’s license before depositing funds. That future is here, but only if you know how to look for it. This archive collects everything that mattered in November 2025: the rollups that actually work, the airdrops you should ignore, the exchanges that vanished overnight, and the legal frameworks—like Wyoming’s SPDI charters—that are changing the game. No fluff. No hype. Just what’s real, what’s risky, and what you need to know to stay safe.
