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?
Bitcoin will not die and it did not yet till 2009. They might be frustrated because of rising in sending fees. And that could be only solve by another altcoin and that was recent reason in rise of Eth , LTC , Dash even ripple. So these top altcoins are still consider best for payment. I am seeing Etherium is now first choice after bitcoin for people use for transactions.
