Right now I am closely monitoring ETH, because the price should definitely go up and in my opinion this token is oversold. ETH is worth much more than 200 bucks and I believe 170 is a good point to fill your bags with ETH.
I think it's oversold, too. It is just followed the other alts in dropping in price, but it now looks ridiculously low against BTC.
ETH is now (last couple of days) starting to show some upwards movement independent of the rest of the market, which is encouraging. There aren't many coins that are strong enough to trigger an alt bull run, but ETH does have that strength.
Sure, ethereum will always be the major catalyst for the altcoin market because altcoins were nothing and popular until ethereum actually created their china for them, and the hype that ethereum created for the altcoins in 2017 really worked and i believe that they are still working on a project that will make that hype boost the altcoin again.
Therefore, ethereum will always remain one of the best coin to actually invest in so that in future, when people are counting their growth in cryptocurrency and investors are happy about their investment, we can also join them and be glad we made investment in ethereum also, same as bitcoin, there is no investment without bitcoin, and that is the number one we should always watch out for to buy at dip.
