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?
That would depends on the person if he will would still show interest on bitcoin or not. On my own opinion if bitcoin dies I would still have interest on alternative coins we just need to study first which alt coin to invest to because there are also alt coins that are scam so we better choose the right one.
