I was looking at ETH and as far as I understand, this coin is mainly successful because of the ICO's nowadays.
ICO's are booming and it looks like it never ends. But what if all ideas are gone and the amount of new coins which use/ need ETH are decreasing. Would this have much effect on the price?
Maybe someone can correct me if I am wrong?
Nope, about the icos that just like a bonus because a lot of people are feeling convenience to use the ethereum caused by the network is ease for use. But that will give any impact to the price. Ico's booming make people are buying ether more and more.
