Why do you think that ethereum is dead?
I don't really think so! Eth price has jumped from 80$ to 150$ within a week! Incredible result!
People say that because they want to scare people away from an investment that could be the best during the next month, even if you invest in ethereum now I do not see how you could lose money since after the hard fork the price of ethereum will go many times higher than its current price, but if they do not want to believe it let them and get the profits for yourself.
Just because ETH has lost so much value (85%-90%) we can declare them as "dead". It's just another obstacles that I'm sure it can overcome in the next couple of months or years.
It has regained and recovered to three digits again, a good sign that investors are willing to invest so I doubt ETH can simply go away. If you have bought it as $80 then you're already in the positive profits by now because it has peaked around $150 at the moment.
