Ethereum is a huge ecosystem, so the Ethereum blockchain can be used in many types of activity, I see a lot of potential in the ETH coin and I can say with confidence that it will be a very good investment!
The advantage for Ethereum is that currently ETH enjoys a complete monopoly as far as smart contract platforms are considered. IT's competitors, such as Stellar, Waves and NEO are showing not much growth, both in terms of development and acceptability. ETH can make use of this opportunity and by the time of the next bull run it can reach new ATH.
