As most have seen when bitcoin drops most alts drop too.
Most alts are measured in value against bitcoin value not fiat.
Will bitcoin always be the king on the cryptos?
If not how would alts become valued without bitcoin price.
hopefully that makes sense.
It's likely that Bitcoin will stay as the King. The value of all cryptocurrency depends on the value of Bitcoin, when Bitcoin rises, most follows, same way when Bitcoin drops (significantly). This alone would likely justify that Bitcoin will stay as it is now.
If ever Bitcoin will be replaced then the new king will be the basis of the pricing of the alts. That's just how it is.
