As of now we are still just few who knows about bitcoin even we are growing rapidly do you think more people are staying in bitcoin.. they are also decreases not only getting more bitcoin holders there are also people who are just staying away in bitcoin after they experience bad things about bitcoin..
About what bad things you are talking about ? Is it investment losses due to bitcoin fluctuation or bought bitcoins but unable to spend it due to unable to find a merchant in local area ?
It could be anything but definitely it is not due to basic bitcoin ecosystem's concepts. So definitely those people will get back to bitcoin if they have experienced any bad things. When bitcoin is getting mass adoption it will be there in every part of this world so everyone will start using it for sure.
