Hydro airdrop is organized in cooperation with the Liquid exchange. It is not an easy crypto airdrop because you will need to register for the exchange and pass the KYC, which means you will need to provide your personal information. For successful participation, you will get 5,000 HYDRO tokens built on Ethereum. Hydro is listed on CoinMarketCap.
The Hydrogen platform allows enterprises and developers globally to prototype, build, test, and deploy sophisticated financial technology applications and products. Hydro is a new component that brings blockchain-based capabilities to the Hydrogen ecosystem and beyond.
