High Voltage is an abandoned cryptocurrency that has been introduced in May 2016. The High Voltage Coin HVCO is a Proof-of-Work/Proof-of-Stake blockchain based currency. HVCO has been designed as a hybrid so that it would prove itself as an efficient and one of a kind cryptocurrency. It is based on the SHA-256 cryptographic algorithm and staking, as this combination is unique on its own and is not used for the majority of coins. The idea behind HVCO was to secure cheap, anonymous and fast transactions on a global scale without limitations. Currently, High Voltage is traded on one exchange market - YoBit and anyone with ETH, BTC, USD, DOGE, RUB can buy it.
