If there is no Bitcoin definitely some name will come up. Cryptocurrency as stated:
I am not sure of that. Remember the "only permanent in this world is change" so I won't won't be surprise if other crypto will take over the seat of Bitcoin but for now, let us enjoy Bitcoin being the king of crypto.
Saying that, even though Bitcoin has a great effect on other cryptocurrencies, there are times when some crypto breaks out from the effect of Bitcoin fluctuation. As you can see, oftentimes we see some altcoin value increasing while BTC price decrease or vice versa.
