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.
When the price of bitcoin goes up then the price of ethereum will start to go up.We will keep an eye on Bitcoin for a while and then invest in altcoins that will benefit us.Out of the many coins we will see in the market, I would choose Ethereum. Because Ethereum is just as popular as it is Ethereum is very good.
there is no need to doubt it because indeed Ethereum is the king of altcoins and investing there will be profitable,
it would be very suitable for long term investment.
