HydroMiner is a sustainable cryptocurrency mining project that uses the Austrian Alps hydropower to conduct cryptocurrency mining on a large scale. To be part of the mining project users need to acquire H3O security tokens. The HydroMiner´s token holders decide if they want to keep the payouts or reinvest them to keep the mining contract live.

The H3O token is an Ethereum-based ERC20 security token used as a contract to use the hydro-mining power within the Hydrominer network.
