The bitcoin repeats its pump and dump cycle but you can never say that bitcoin will be dead or of no value. This can never happen as we can see the future monetary system being controlled by bitcoin.
It might happen though I am not saying that it will, but still evev if the chances are low, the possibility is there. Also, don't say thay the future monetary system will be controlled by Bitcoin since we all know that the government will not accept a volatile and decentralized crypto currency, if that happens though, the whales can control countries and economies, you don't want that.
