$ 300 is a small value if you look at the ATH they have already achieved. of course, ETH will be easy to achieve if growth is still gradual. but it will be different if bitcoin stops continuing the current uptrend. it will have an impact on the value of ethereum in the market.
yes, actually not all altcoin depends on the increase of the price of bitcoin itself, generally it depends on market demand. but seeing the fact that the increase in the price of bitcoin is currently having a positive impact on some altcoins especially especially with ETH. I observe that ETH currently has good price growth, even I personally will never hesitate to add an ETH altcoin bag for the future.
