Will ethereum price go down after ethereum casper project come out? When will the project come online? What do you think it's going to effect original ethereum after?
There is no connectivity behind the ethereum price fall and eth casper. There are people invested on the ethereum recent by using the price fall in the market. I am not sure that this ethereum will be dumped more in the market or not but sure may find the right price now.
If you want to find the coins value more cheaper there would not be wait for more time. As soon as possible buy the coins you want.
You may check the project to consult when it will come to online.
