Currently the price of ETH acts as an initial rise for the bull market thus impacting the rise of other altcoins, an increase between the prices of altcoins and bitcoins will cause a higher and more stable market rise at prices above $50k before reaching the next bullish moment price.
The rise in Ethereum at the moment doesn't have a big impact on other altcoins, because most other altcoins are more affected by the rise caused by Bitcoin, so market conditions look more stable and healthy, so this is what everyone should really be aware of.
