During the first ICO HydroMiner raised 7346 ETH by giving out the H2O Token. H2O is a voucher for mining time in the facilities of HydroMiner. One H2O will grant a minimum of 5 kWh of energy, but the team can decide if they allocate more kWh due to the hardware and market situation. Since February 2018 the mining portal is open where H2O Tokens can be redeemed towards mining time.
HydroMiner offers GPU and ASIC Mining not only for H2O Token holders but also against EUR / USD and cryptocurrencies at the shop.
Currently, customers can decide if they want to mine Bitcoin, Bitcoin Cash, Ether, Ether Classic or Zcash. More currencies will follow.
All non-issued H2O Tokens were burned, as stated in the whitepaper, on 9th May 2018, find the txH here.
