Ethereum is a great short term investment opportunity. Long term? I don't know, because I don't think they will be able to fix its network slaking issues. For that to happen, they would have to completely dump the ETH blockchain and move over to something new & imporved with future scaling in mind.
EOS is one platform that can/will eliminate the need for ETH, NEO, and any other smart contract platform. That's how unique EOS is. Will it kill off ETH? Probably not, but it should co exist quite nicely together.
EOS is defintely a great platform because it allows users to develop and deploy the platform as a host, unlike BTC and ETH. Specifically ETH will also develop into something else with passing time if it has to hold the horses with the advancements.
The market will never be like this than it is now. We will have multiple kings with multiple lords favoring them. So it's going to be a huge blockchain on its own. Haha! Yours was a nice & juicy comment. Cheers bro. :D
