Hello!
If bitcoin died do you think people will lose intrest in other cryptos aswell? which altcoin would you invest in if there were no bitcoin?
i thinks its not. because if ever bitcoin hardly drop from its current price now, all investors are do switch to the other altcoin that has more potential than bitcoin, and all that interest will not lose instead it will grew like how grows our profits in bitcoin, crypto world is so wide, your mind cannot reached how wide this crypto world is, maybe theres a lot of trials/loosing/mistakes in crypto before you got find the right one but in the end you will earn profits more than what you expected before.
