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.
We can not say, I think, it is easy to determine on small scale, like number of bitcoiner on one country, as for me there are 159.890 members already registered on our local exchanger which is all of members need to provide their identity to open an account. Say, maybe conduct a survey or something or watch the bitcoin market.
