Aquariuscoin was released to the public in 2015. It is a decentralized cryptocurrency. Aquarius is the eleventh zodiac sign in the horoscope and is considered to be a progressive, original and humanitarian sign. In the beginning, Aquariuscoin was built on a hybrid between Proof of Work and Proof of Stake algorithm, but as time passed by, the team switched to Proof of Stake only. One of the few differences is that there are no block rewards in the POS system, but instead that miners receive 100 coins after destroying a block. 42,000,000 ARCOs are in circulation. Staking earns a 6 % annual interest. ARCO implements water sustainability systems, clean energy systems, and blockchain identification. Aquariuscoin can be exchanged on various platforms like YoBit and Cryptopia.
