Bitcoin can only die when people ignored and refused to invest in it, which can only occur when they fine interest in other coins believe
many people has begin to lose interest in bitcoin already.You're talking about a bunch of individual people, but the majority of people and especially companies -begin to- show interest in Bitcoin. Right now there has never been so much attention for it - don't confuse it with the bubble. When Bitcoin goes down in red numbers, the rest also follows. That means Bitcoin is still the king.
