We are at all time high price level so it doesn't make any sense to comment that bitcoin is dead or will die in future as price has started to increase now and same we will see in coming years too when more people will start investing their money in bitcoins.
Bitcoin is dead only for those people who have made huge loss in the past by investing their bitcoins at a wrong place and now they are blaming bitcoins for their loss and that is reason they are spreading negative news about bitcoins.
