what you think about constantinople fork? its coming in 1 day.
here is 2 fact :
1 - new ETH will 2 in per block, this is good. (circulation suply will grow less then now)
2 - (PoS) algorithm. i think SEC and PoS arenot friends
your predict about 2019 and ETHEREUM
Ethereum devs are taking a lot of precaution to make this Constantinople hard-fork successful last week they delayed their hard-fork due to security issues. I have not seen issues of SEC with any POS algorithm coin except privacy coins. IMO after the hard-fork price will grow gradually & it will also depend on the users experience/reviews ho faces scalability.
