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 it is hard to determine the exact or actual number of bitcoin users. There are accounts which are actually owned by just one person so it is difficult.
