By the fact that ethereum is the digital currency that has the second biggest market cap of cryptocurrencies, then it's safe to say that ethereum is really a good investment. Ethereum can not simply go up on the second spot if it is not a very good crypto to invest to.
yes, strongly agree with you Ethereum is very worthy for investment, Ethereum development is very good from time to time more and more fans it can be seen in a market average of ICO project using Ethereum so I firmly believe the future of ETH is very bright.
