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?
Possibly people will really lose interest into other type of cryptocurrency once Bitcoin will be permanently down or being abolished by the government. But if there will be a great opportunity and observable potential to grow that an altcoin will provide such thing like what Bitcoin have done, possibly, they will just move into other cryptocurrencies and continue the journey of getting along with cryptocurrencies even Bitcoin was gone or without the presence of Bitcoin.
