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
It doesn't make sense to see if POS are not friends with SEC. SEC is only aiming the utility usage of coin and SEC never care so much about which consensus that used by a platform just like ethereum.
Less inflation that will make sure the price can go even higher.
