Just like bitcoin and other cryptocurrencies Ethereum also experiences a bubble and that article just stated that if Ethereum loses grip of the 330$ value it will continue to decline. But after seeing the charts lately Ethereum has made it back to over 330$ and it has already become stable. This is a sign that the bubble had stopped and we will see another increase in value in the coming months. But let us just be careful since a bubble may hit Ethereum again since. But investing in Ethereum is ones decision, the articles are just our guides but it is not the truth of all.
