They are kidding when they says that bitcoin is dead, because until now this crypto currencies are healthy fluctuating in the crypto currency industry. Other than that its impossible to die bitcoin because their foundation was already fixed and strong, they can support it whatever happen. Otherwise more users are believe and trust to this coin so I can't see any problems with that. Even bitcoin are experiencing problem they can handle it quietly that's why more supporters of this coin are still holding this coin even their value are fall down.
