Earlier that was not the case, earlier whenever Bitcoin goes up, it used to pull all the cryptos with it but now things are changing, Ethereum clearly is now out of the league of Bitcoin and is in its own now and is pulling the finance from BTC.
I think Ethereum is the only coin now, which does not depend on the price of bitcoin and is independent. I don't see any other independent coins.
a comparison of these two coins are already evident from the price.
the price is still below the Ethereum owned Bitcoin,.
This triggered Bitcoin has more interest in this than the Ethereum become forms of support which influenced the development of existing coins.
