There are a lot of helpful and meaningful altcoins so your Thread-Title is not that right. The diversity of the altcoins is extremly high.
Indeed, even with the altcoins today, they are valued without Bitcoin's pairing. Like Ripple, NEO and LiteCoin and other top altcoins.
Soon, there would be less market droppings because when Bitcoin dropped it will no longer drag down altcoins to it's price adjustments.
Yes. Bitcoin is really taking the cake when it comes to attention. But there are so much good projects together with altcoins out there. Unlike bitcoin, altcoin comes with diversity. This what makes alt so good for us. There's a bunch of investors and a bunch of new fresh developments are coming through. It's just that most of them are getting dragged down by bitcoin during price dips but I don't think it will last because some alts are becoming better and better with their platform, system and other developments that are being done.
