I am wondering if there are coins that are independent to the Bitcoin price? Like, if Bitcoin's value increases, the altcoin will not increase at the same time Bitcoin does. Or maybe, I am wrong that the price of Bitcoin doesn't have any effect to the value of altcoins? Please enlighten me with this topic. If there's any coins that are independent, what are the benefits that you can get in investing to that altcoin that you can't get in investing in Bitcoin?
You are right that the price of Bitcoin can affect the price of altcoins. All altcoins are still dependent on Bitcoin's price because most altcoins in the market have no trading pair directly to usd or fiat, and even some altcoins have, only few exchanges lets you buy and sell altcoins using fiat directly. I think Ethereum is somewhat independent since there are numerous exchanges that have ETH/USD pair. What are the benefits? if a coin is independent to Bitcoin's price then the advantage is when Bitcoin price fall or crash, it will not get affected, meaning the price of other coins are dropping while the independent ones can possibly go up or no effect at all.
