It is likely that ethereum might recover it's market value, may be not to hundred percent recovery but there will be recovery. Ether dump was surprising and tragic for big holder like me, I hope I get at least 50% of my value back!
I do not even dream about the price of $500-600 yet, but if after hardfork the price goes up and reaches $300 by the end of January, then I will again have hope for approaching the former heights
