First of all, Bitcoin is not an altcoin. Secondly, I think that at the end it will be great again. Because there will always be the people who have faith and trust in it.
I believed you misunderstand the OP statement because he was asking question about the altcoin that have capacity to be the new crypto king after the crash of Bitcoin which the OP predicted will happened. However, i believed such crash situation won't happened to Bitcoin.
