In my opinion, It's ETH. The price of ETH is around $850 in this days, and is the 2nd largest crypto by market cap behind BTC. Also, The largest open source blockchain initiative backed by over 300 companies, many of which are Fortune 500 companies like JP Morgan, Accenture, and Microsoft. They all believe that ETH is the best platform to create enterprise-level software on the blockchain. According to road-map in 2018, ETH has many technological upgrades relating to scalability, privacy, and decentralization coming to its platform in the next year. In particular, their upgrade Casper, will switch ETH’s consensus algorithm from Proof of Work to Proof of Stake, which will greatly reduce both the environmental impact mining has and the growing circulation of ETH, thereby making each coin more valuable.
