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?
Yes the prices of Altcoins tend to follow Bitcoin. This is mostly due to Altcoin/Bitcoin pairing being traded. Every major exchange offers BTC trading pairs. Because BTC is the top coin being traded for other alts in terms of market cap, volume, and general popularity, it is thus at the center of the crypto economy and has some gravity behind it. Therefore, the prices of Altcoins mostly follow Bitcoins prices.
I agree with your points. There is a direct correlation between Bitcoin and the altcoin market and people who don't agree must do their research. I have observed that Bitcoin and altcoins are directly proportional to each other majority of the time and inversely proportional to each other minority of the time. This is why majority of the crypto community get excited everytime they see Bitcoin move upwards since they realize that this would most likely help almost all altcoins rally along with it. I don't see this changing anytime soon which is why I continue to be optimistic about the future of Bitcoin and the altcoin market.
