Is there a way to determine the number of people who are actually using Bitcoin till date? Who would have access to such information? Meaning a way to find out, how many new people have used Bitcoin in 2016 , so that we can say exponential growth is natural not artificially created by hoarders.
I think there is no way to determine this. there is nothing that can determine the actual growth accurately but i bet you there is increasing growth of people because of rising price.
I agree with your statement because i also think that the actual number of using bitcoin is uncountable and i also belive that the actual number of people using bitcoin is increasing day by day.
