I'm not sure people are saying "bitcoin" is dead...I have never heard about except here in this topic.
And of course the price of bitcoin has nothing to do with "lifity"
i agree with you that people can say that bitcoin is dead , because everyone like to bitcoin and want to invest their money in bitcoin because bitcoin are going rise up its price too much faster day by day and there is many people who have not any knowledge about bitcoin because they says that bitcoin is dead if they know about bitcoin then i hope they stop to saying that bitcoin is dead.
