Crypto Exchanges and Blockchain Trends in November 2025: Dead Protocols, ETFs, and DeFi Realities
When you look at the crypto exchanges, platforms where users trade digital assets like Bitcoin, Ethereum, and niche tokens. Also known as decentralized exchanges (DEXs), they range from trusted giants to abandoned shells with zero liquidity. In November 2025, the market didn’t just move—it cleaned house. Dozens of once-hyped platforms vanished overnight: BiONE, O3 Swap, Ultron Swap, and StarSharks all turned into digital ghosts. Their tokens? Worth pennies. Their communities? Silent. Meanwhile, real infrastructure like THORChain and SushiSwap on Polygon kept running, proving that trustless, non-custodial systems still matter when the hype dies.
The blockchain, a distributed ledger technology that records transactions across many computers without central control. Also known as distributed ledger, it’s the foundation of everything from Bitcoin to DeFi apps isn’t just about speed or low fees anymore. It’s about structure. Modular blockchains—like those used by Polkadot and Cosmos—split tasks into layers, letting each part scale independently. That’s why projects like THENA FUSION and SakePerp can offer 60x leverage and instant settlements without collapsing under load. And it’s why Bitcoin’s 10-minute block time still works: it’s not slow, it’s deliberate. High hash rates make mining harder, which keeps the network secure. No one controls it. No one needs to.
Then there’s regulation. In the U.S., crypto businesses now need more licenses than a taxi driver. FinCEN registration, BitLicense, money transmitter permits—it’s a maze. In Singapore, Binance offers low fees but no MAS license. In Iran, traders use VPNs and get caught. In Turkey, the 2021 payment ban still stands, but $170 billion in trading keeps the doors open. These aren’t theoretical risks—they’re daily realities for users. And they’re why the Bitcoin ETF, a regulated fund that tracks Bitcoin’s price without requiring users to hold the actual coin. Also known as spot Bitcoin ETF, it’s become the gateway for traditional investors and the Ethereum ETF, a similar product that tracks Ethereum’s price, approved by the SEC in early 2025. Also known as spot Ethereum ETF, it’s the first major step toward institutional adoption of DeFi assets changed everything. They didn’t make crypto safer—they made it legal. And that’s why even meme coins like GM Wagmi and LEE still have users: people are betting on culture, not just charts.
What you’ll find below isn’t a list of trending tokens. It’s a graveyard and a toolkit. You’ll see exactly which exchanges are dead, which DeFi tools still work, and how to spot the next scam before you lose money. No fluff. No promises. Just what happened, why it matters, and what to do next.
