Don't be surprised that other altcoins will not boom as soon as ETH gets to $4,500 because most of the altcoins are just totally dependent on the capacity of the project owners to also influence their project so that it can gain recognition and follow the trend but when they are not even doing anything to make the project get attention there's no way it will boom, don't be surprised that only a few better altcoins will pump when the market becomes more bullish.
