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?
Now we have the 21. of January and no big moves to the upside have been made, except from the rallying back but that more a relief move after the signficant pullback that the price had been going through beforehand.
