I think most of people who are called their self as a true believer of bitcoin are already disappear because now we see that the value of bitcoin is in the lower price value rather than last year. I think the true bitcoin believer is the man who are still working and investing in the bitcoin even if the  value is in that situation. All we know that bitcoin is full of risk once you will take that risk specially the risk that we have today we will call them a true bitcoin believers but the reality most of them was already left the market because most of them are afraid to take a risk or to commit a loss.
