ETH is inflationary, after PoS casper inflation will be added so it will never have a limited amount of supply. They didnt even decide on what the inflation will be. Not a long term holder coin.
the whole point of ethereum, meaning the basic thing they have started their coin on was to have a big supply so that with that big supply they could have a fake market cap and because of having a big market cap stay on top (number 2) and on top of the news.
that is also why they never thought or said anything about the max hence the unlimited supply for now.
if things become hard to manage and sell pressure becomes big they will flip the switch once again and hard fork. the only positive side is that we can see our coins double.
