EOS has all the attributes of a great project and the potential to rise to one of the top 3 blockchains in the world. The lessons brought forward from previous projects are a huge advantage over most blockchain projects.
It's hard to put a price on EOS before its blockchain is live and running in 2018. That said, however, EOS is a project every investor should be watching. If it lives up to its plans, it has a potential market cap of at least $20 billion.
