if no one spends bitcoin maybe altcoins will be gone, but chances of that happening is very small, remember bitcoin is cryptocurrency a great for the future
Altcoin will gone and bitcoin will die, as such no one is spending money, I think it imposible, bitcoin created not to be stored but used for the transactions.
bitcoin is not going to die, as bitcoin is one of the most popular crypto currency of the world therefore it cannot die, as it is a decentralize currency and not belong to a state or person or a group who can banned it and people will stop using it, bitcoin is free from all these worries therefore it will continue for ever and not gong to die.
