There are a lot of other coins with similar profit. I'm going to switch to Ravencoin, Monero, XZCoin or something else if Ether will be unprofitable. But I think that its price will rise after successful Constantinople update and profit in fiat money will be the same.
I doubt it will happen...
Yup.
Prices will remain the same or even go lower depending on BTC of course. Classic supply and demand theory only works on necessity or rare goods (food,water,clothing,shelter,jewelery etc). No one is using ETH for anything so why would anyone want ETH other than hodling. If less supply = higher price then may I present you with Bitconnectttttt.
I wonder who/what will be the next scapegoat that ETH bagholders will blame next.
