I've asked myself same question over and over again until I took time to study the market trend. Bitcoin is the King and whatever moves the King makes, the kingdom (Altcoins) suffers positively or negatively. Let's reason together, what happened to altcoins when BTC tanked from 20k USD to 13k USD and finally to 6500USD, almost all altcoins suffered as well. Even ETH that was expected to hold firm also dropped in value. BTC controls the market. When it's stable then altcoins can grow organically.
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?
