Where could I store my assets in an emergency if there are no more bitcoins?
And you think if there's no bitcoin other coin would survive??
I can say with all assurance that if there's no bitcoin today all other altcoin will fold up by dumping 99 percentage.
I disagree with your point of view. If there is no Bitcoin, there will be another decentralized cryptocurrency that will function like Bitcoin. Blockchain tech is inevitable. It is bound to be created and discovered. If the first decentralized blockchain is not named Bitcoin then it will be named something else and the same pattern will happen. Besides, if there is no Bitcoin then the capital injected on Bitcoin will be dispersed to the altcoin market. It is a matter of equilibrium.
