A Chinese student studying in the United States shared a picture, saying that he has a small inconspicuous CA white box hanging on his balcony, and he earns a passive income of $17 a day, which amounts to five to six hundred dollars a month, just enough to cover his rent and meals for the month.

The comment section exploded—some asked if he was involved in any gray market activities, others asked if it was a mining machine for cryptocurrency. He calmly replied, "I just hung a weather box; it uploads weather data every few minutes, and the system sends me tokens."

This project is called CAILA. It is not a meme hype, nor is it a Ponzi scheme; it is a real-world project that integrates AI + DePIN + blockchain, focusing on the concept of 'On-Chain Meteorological Officer.'

In simple terms, you hang a small device called Marco on your balcony. It regularly collects data such as temperature and humidity, uploads it to the blockchain to train AI models, and you—just by 'providing real-world data'—sit back and wait for your tokens to be sent daily!

This little white box, Marco, does not need to be plugged in, does not require Wi-Fi, and does not require technical knowledge. As long as you hang it up, it will start working, automatically uploading data, and then the system will reward you based on 'data quality + timeliness + location scarcity.'

From my own testing, one device produces approximately 18-22U per day, which translates to 500-600U of pure passive income per month. This is more stable than trading altcoins for a week!

CAILA's narrative is more robust than most projects: airdropping devices, launching in Binance Alpha observation zone, collaborating with FourMeme for trading competitions, integrating into the DePIN data market, organizing cross-chain GAS airdrops, and working with major projects like Lista DAO and THENA for liquidity incentives, step by step revitalizing the ecosystem and creating a closed-loop with the tokens.
