When you look at Bitcoin, the original and most widely used cryptocurrency, often used as a digital store of value and market benchmark. Also known as BTC, it remains the heartbeat of the entire crypto market. In September 2025, Bitcoin didn’t just move—it redefined what traders expected. After hitting a new all-time high above $120,000, it pulled back sharply, but not because of panic. It was a natural correction after a massive institutional buy-in from ETFs and sovereign funds. This wasn’t a crash. It was a reset. And for everyone watching, it meant one thing: the market was getting serious.
Right behind Bitcoin, Ethereum, a decentralized platform that runs smart contracts and powers most DeFi and NFT projects. Also known as ETH, it is the engine behind nearly every major blockchain innovation today. Ethereum’s September upgrade, called "Nebula," cut transaction fees by 60% on average and made layer-2 networks like Arbitrum and Optimism faster than ever. Developers rushed to deploy new apps. Users noticed the difference—gas fees dropped from $5 to under $0.50 on most transactions. This wasn’t just a technical tweak. It was the moment Ethereum stopped being a bottleneck and started being the backbone of real-world use.
And then there were the airdrop alerts, free token distributions given to users who interact with new blockchain projects, often as a way to bootstrap community adoption. September was packed with them. The Solana-based DeFi protocol "Lumen" dropped 500,000 tokens to users who held NFTs from its early beta. A new privacy coin, "Cipher," gave away 10% of its supply to anyone who ran a node for a week. And yes—some were scams. But we flagged the real ones. No guesswork. Just verified claims you could still claim by the end of the month.
