According to Mark Johnson, in Quora, "It is possible that Ethereums price will increase after the EtherZero (ETZ) hard fork on the 19th of January"
What do you think?
If to take an example bitcoin then I do not think that the etherium will grow after a fork, but in this market very honest unpredictable things that I will not be surprised to ethereum grow after a fork
really, a lot of things that usually unexpected appear. so I can only try to stay calm and hope that nothing bad will happen to eth after the hard fork.
