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.
That's right dude, it is impossible to trace the actual number of bitcoin users, although bitcoin is pseudo anonymous but still untraceable.
And its hard to calculate the actual numbers of the user, especially everyday there is new comer signing up in the forum just to try to invest bitcoin together with the some whale investor in this field of industry.
