Ethereum will be huge in five years. It's still so early to tell because there aren't enough consumer to use all the decentralized apps that are being developed. But in five years all that will have changed. Once people start being interested in these crypto's and start seeing the benefits that the blockchain technology is offering, the more will start joining. It's a fact and I expect this to happen within less than five years. When this happens ETH will be there waiting for all the consumer adoption and that will skyrocket the price to even further gains. It has already performed great and is one of the best performing coins. I'm sure the trend will continue and we'll see a thousand fold increase in value in the coming years. Who know's how big this can get.
