For me, Ethereum is one of the best altcoin, it's always worth to invest. Ethereum has excellent blockchain technology, it is the foundation of so many ICO projects. Every day Ethereum has a lot of deals showing that this altcoin has great potential. I believe in the future Ethereum will continue to grow and compete with Bitcoin as the throne of the cryptocurrency market. At present Ethereum prices are very low, only about $ 460, this is the time for us to invest in ETH. I believe that long-term investment in ETH will bring a lot of profit for us.
