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 by collecting every wallet and registered account can predict the number of each user, even if it does not really match. because everyone can generate some wallets and accounts.
