To me it doesn't matter whether it's named has bitcoin or whatever .as long people using the internet for their transactions there will always be a need for some .
i think if bitcoin change it name into another name it will always use people as currency here in internet because it is good currency where investors can do gambling and trading where they can grow their money as easy they want if someone stop using bitcoin then for him/her is the end of bitcoin for him because he don't want to continue anymore
