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?
From the fundamentals, a lot of altcoins should have a price pattern that is independent from the Bitcoin's price, since a lot of them have different tech and consensus algorithm. However, from technical analysis, it's possible to see that most altcoins have a similar response to variations in the Bitcoin's price.
If you don't know the tech behind these alts, it's better to hold Bitcoin, since there is a high risk that you can get burned by dumping it.
