Ethereum have said to be rising not because of ethereum fork rather, another reason entirely. The bull market of ethereum may not happen because of the fork. After the fork however, there is a possibility that ethereum will rise in price.
I completely agree with you, since the ethereum Classic Vision has nothing to do with the update of Constantinople, since it is not an official hardfork. And this in turn does not affect pricing today.
A day ago, ethereum was $ 150, and now it has dropped to $ 126. And as now applies to all those forecasts that you talked about the prospects in January. It's all a lie and again a lie.
