I don't think 75% of bitcoiners say it is a bubble or something like that! What did mean you by bitcoiners? Because Bitcoiners never worried about Bitcoin low price, they have enough confidence that everything is ok till now! Who judge Bitcoin's price by seeing the previous year's high pump, they are not bitcoiners!
Yes, you are right. Any one who believes bitcoin is now a bubble leaves the market. Why should such a person spend the money and the time on something which is bubble?
Most of the current holders are the true believers.
We do not blame other people who says this in bitcoin because have lack of knowledge about crypto currency and i think they are the one who lately adopt crypto currency that is why they always think bitcoin is an altcoin.
I agree that believers continue to hold their coin like me.
