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
Miners will hate it but PoS will allow for a healthily low levels of inflations in Ethereum, not to mention that staked ethers are not really tradeable, so the float will be lower and any buying pressure will positively influence price more than it does not. I'm bullish.
