I think ethereum is a true outlier and it is the only crypto-currency believed by experts to be able to overtake Bitcoin Market cap in the near future. Ethereum started in 2013 and had 40x growth rate over the last two years. Its platform allows creating a smart contract that runs on a decentralized network and runs exactly as programmed without any possibility of downtime, fraud, censorship or any third party interface. The team behind Ethereum is really exceptional. They are doing an amazing job to show the real potential of the Ethereum. Also, the degree of adoption of Ethereum is phenomenal at the moment. Many developers are working on apps that use the potential of smart contracts. If one cryptocurrency can make it big, it’s Ethereum. If already went over 1000% over the course of couple of months and it could go 1000% more over the next few months – that much potential this cryptocurrency has.
