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
There are only two options, or it will reduce capitalization and return the ether to third place, or, more likely, a slight decline with a subsequent increase in demand. And this option will strengthen the faith in him and most importantly will give confidence for the update.
