holding ETH really benefits having a long-term investment and the price is soaring up not just BTC but also Ethereum which is great to hold and accumulate. And I think the price of Ethereum could reach more than $5000 if BTC rises up more but I think it will also affect some other altcoins.
Even though the transaction fee of ethereum is going much higher it's still one of the greatest altcoins to hold and has a lot more potential in the future.
There is no doubt that the most reliable and profitable coin in the market after Bitcoin is Ethereum at the moment and in the future, if Bitcoin grows, Ethereum will grow a lot, but if we see it break, if the market falls, and if Bitcoin goes down further then it will have the biggest effect on Ethereum. So my advice is to set your limit using the DCA method and buy so that if the market drops, you have more money left for investment, apart from Ethereum, there are BNB, SOL, and some other trusted coins that can be invested in.
BNB and SOL are the coins after Ethereum on the altcoin side. Other altcoins and meme coins may not be as reliable as these three if one wants to hold them for a long period.
