I think you’re right to be bullish about EOS and many are calling it an Ethereum killer. As to it’s Proof of Stake, this is something Ethereum is working on and my understanding is that all coin with a PoS element are actually a hybrid of PoW and PoS, rather than just PoS. Ethereum’s scalability issue could also be resolved soon due to the Raiden Network and later on by Plasma. However, EOS is certainly a good project. 👍
