That is true, Ethereum is one of the major alt coin and others follow. Considering it premium value especially in 2018 when the market value rose attention shifted towards it, and now that it price is falling I totally believe that it is an opportunity to buy or invest more into this coin because it will eventually increase again in price. See it is the largest altcoin when compared with the bitcoin, it stands a chance of remaining in the digital market for longer period of time.
