Actually death of altcoins would make people lose their investments. They would also not be able to convert their altcoins into bitcoins before they are dead. This would leave them with no money. But yes, in case the investors predict the future markets and convert their altcoins to bitcoins before they are dead than it might be beneficial for the price of bitcoins for the long term
Most altcoins are already dead beyond redemption
And people have already lost their investments. It just happens that their brains can't catch up yet and finally come to terms with this sad fact. As I'm strongly inclined to think, this has a lot to do with the so-called sunk cost fallacy, according to which a sunk cost is money paid that cannot be recovered. The meaning is that people who already invested their hard-earned cash in shitcoins refuse to accept the truth that the money is gone, as in gone for good, while they continue to cherish a hope of getting it back one day thereby making their life only worse (we all have been there, and probably not just once)
Bitcoins have no intentions to exit the markets and hence it has made a lot of investors stay tightly close with bitcoins and in any case where altcoins are on the verge to die, those people would be instantly supported by bitcoins to stabilize their financial situations
If the altcoins these people invested in have already lost any value, Bitcoin rolling high will be of little consolation to them
