When Permission.io, a blockchain-based advertising platform that let users earn tokens for sharing attention data. Also known as PMT token, it tried to flip the script on digital ads by paying people instead of tracking them without consent. launched its airdrop in 2021, it looked like a win-win: users got free crypto, and the platform built a user base. But within two years, the project vanished from major exchanges, the app stopped working, and the token price dropped to near zero. This isn’t just a story about one failed airdrop—it’s a warning about how most blockchain advertising projects never deliver on their promises.
The PMT token, the native currency of Permission.io’s ad network. Also known as Permission token, it was designed to be used within a decentralized ad marketplace where users controlled their data. was distributed to users who installed the Permission.io browser extension and allowed ads to be shown on their devices. You didn’t need to buy anything—just install, run, and wait. Thousands signed up. But the token had no real utility outside the app. No major exchange listed it. No DeFi protocol integrated it. No one outside the small user base cared. That’s the death sentence for any crypto project: no demand, no liquidity, no future.
Permission.io wasn’t alone. It was part of a wave of 2020–2021 airdrops that promised to disrupt advertising with blockchain. Projects like Brave’s BAT, a token rewarding users for viewing privacy-respecting ads. Also known as Basic Attention Token, it succeeded because it integrated directly into a popular browser with real user traffic. actually worked because they had a built-in audience. Permission.io didn’t. It had no browser, no major partnerships, and no clear path to scale. Meanwhile, the airdrop recipients were left holding a digital asset that couldn’t be spent, traded easily, or even verified on a reliable blockchain explorer. The whole thing felt like a marketing stunt dressed up as innovation.
What’s left now? Nothing. The Permission.io website is gone. The app doesn’t load. The token trades on obscure decentralized exchanges at fractions of a cent. And the people who claimed the airdrop? They got a lesson in how not to invest in crypto projects that sound good but have no real product. If you’re looking for a real airdrop today, skip the ones tied to obscure ad networks. Look for projects with active development, real users, and listings on major exchanges. Real value doesn’t come from free tokens—it comes from real utility, and that’s what you should be chasing.
