Crypto Airdrop 2021: What Happened and What You Can Still Claim Today
When you think of a crypto airdrop, a free distribution of cryptocurrency tokens to wallet holders, often to grow a project’s user base. Also known as token giveaway, it was once the easiest way to get into crypto without spending a dime. In 2021, everyone was chasing them—DeFi projects, NFT platforms, even meme coins handed out tokens like candy. But not all airdrops were created equal. Some gave users real value. Others vanished overnight, leaving wallets empty and hopes crushed.
Take the SPWN token, the native token of Bitspawn Protocol, a gaming-focused blockchain project that ran a 2021 airdrop. Also known as Bitspawn airdrop, it was one of the more organized drops—but even that faded fast. By 2025, claiming SPWN became nearly impossible, and the project’s website went dark. Meanwhile, the RACA airdrop, linked to the Metamon NFT marketplace and Radio Caca’s ecosystem. Also known as Radio Caca tokens, it’s still active today, with users claiming rewards as late as 2025. Then there’s PolkaWar (PWAR), a game project that gave away tokens on CoinMarketCap but never delivered a working game. Also known as PWAR NFT game, it’s now worth less than a penny. These aren’t just stories—they’re lessons.
What made some airdrops survive and others die? It wasn’t just hype. Projects with real utility, active communities, and transparent roadmaps lasted. Those that relied on social media buzz alone? They collapsed. Scammers learned fast. Fake airdrop sites popped up pretending to be RACA, SPWN, or even Baby Doge Billionaire—each asking for your seed phrase, your private key, or a small fee to "unlock" your free tokens. No legitimate airdrop ever asks for that. Ever.
If you missed the 2021 wave, don’t panic. Some claims are still open. Others have been replaced by newer systems—staking, farming, or play-to-earn rewards. The key isn’t chasing every drop. It’s knowing which ones still matter. Below, you’ll find real reviews, step-by-step claim guides, and sharp warnings about what to avoid. No fluff. No promises. Just what actually happened—and what you can still do about it.
