ETH is the best altcoin, it is always recommended to buy and hold this coin as many as possible. But the price increase of ETH, mostly depends on the Bitcoin price trend. If you see it increased above $1,900 recently, it is because of the increase in Bitcoin price. After Bitcoin returned to $30k, ETH and other altcoins are following the increase, too. Now, I guess Bitcoin price will drop again below $30k, the uptrend is over. You must be aware that ETH price is following it, too. We can see the price of ETH is already below $1,900 again.
