Dissappear as in what manner? I really don't know why people have been putting together such news and I know maybe they want BTC to die but this will never happen as the blockchain lives.
The blockchain lives even without bitcoin, but I don't think people who made bitcoin successful will just allow it to die.
Bitcoin's success made this whole crypto market grows, and even if some altcoins are dying, there's a new one that will be created and as long as bitcoin holds dominant rate, the market will remain strong and has a potential to continue to grow bigger.
