the simple answer is because Ethereum is considered the most top and trusted altcoin, even though as many altcoins emerge every day, Ethereum's position remains the top one. With the current market cap, other altcoins are still quite far from replacing it. but indeed in terms of technological development and achievement, actually Solana, BNB, and TON have quite significant developments, but still can't replace Ethereum's position. the value of ETH is indeed that good, the same as Bitcoin, the value is that high, but still, Bitcoin is number one.
We can say, in my opinion:
Bitcoin -> the best crypto
Ethereum -> the best altcoin
So ETH does have its own special space for me in investing. Although not much, but at least its portion should be bigger than other altcoins.
Oh yeah, right now the price of ETH is still around $2,439, still around 50% of Ethereum's ATH. So if you want to enter Ethereum right now, it's still very worth it, at least to reach the target at the previous ATH price. especially if it can really go up to $7k, wow, this will be much more promising, even if we enter now.
