What is Cosmos?
Cosmos is a decentralized network of independent parallel blockchains, each powered by Tendermint.
4 Elements in Cosmos
Atoms - a license for holders to stake and vote
Validators - responsible for committing new blocks
Zones - blockchains that can exchange values through Hubs
Hubs - A blockchain that let Zones work together
Positives for Cosmos
Negatives for Cosmos
Bottom Line: Tendermint has been in development since 2014, while several projects will be using it (CEEK, DATA), it is still not complete as of March 2018.
Cosmo fundraised (not ICO, hopefully SEC agrees) $17 million in just 8 minutes, but will probably be released after EOS, which ICO 2 months after. It will be interesting to see who will be more popular in 2018 (or if we are just still talking about Ethereum).
