BlockGem Crypto Archive: April 2025 Coins, Exchanges, and Airdrops

When you’re tracking the crypto coins, digital assets built on blockchain networks that trade on exchanges and power decentralized apps. Also known as cryptocurrencies, they shift fast—new ones pop up, old ones surge or drop, and the rules change without warning. April 2025 was no different. The market didn’t just move; it restructured. New coins tied to real-world use cases like AI data markets and decentralized identity gained traction, while older tokens struggled to keep up. If you weren’t paying attention, you missed the shift.

Behind every coin is a cryptocurrency exchange, a platform where users buy, sell, and trade digital assets, often with varying fees, security levels, and supported coins. In April, a few major exchanges rolled out new staking options and lowered withdrawal fees to lure users. Others got hit with regulatory delays, causing liquidity issues. You didn’t need to guess which ones were safe—you just needed to know which ones were still operating without red flags. And then there’s the airdrops, free token distributions given to wallet holders as rewards for early support, testing, or community participation. This month, over a dozen legit airdrops dropped, mostly from Layer 2 projects and new DeFi protocols. Some required simple actions—like connecting your wallet or joining a Discord. Others had hidden traps. Not all free tokens are worth claiming. BlockGem cut through the noise. We checked each one: contract audits, team history, tokenomics. No guesswork.

What you’ll find in this archive isn’t just a list. It’s a snapshot of what actually mattered in April 2025. We covered coins that broke $100 million in volume, exchanges that improved their KYC flow overnight, and airdrops that paid out in real value—not hype. No fluff. No recycled news. Just what you needed to know to stay ahead, not just caught up.
