EOS is a really promising and exciting 3rd generation blockchain platform that is slated to compete with the likes of Ethereum, NEO, Cardano, etc. They have novel (and experimental) approaches to the problems plaguing gen 2 blockchains - scalability, interoperability, and governance. EOS is targeting its official launch in mid 2018 and at that point well be able to see if their choices of on-chain governance (voting), 21 block producers, 0 transaction fees, parallel processing, etc. will actually work in practice.
In my opinion, one should do their own researches before buying. Have a close look to the Projects before you invest money. Real world usage and adoption should be the most important things to watch out for.
