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 tell how many people use bitcoin. I guess there must be a Chinese Bitcointalk equivalent. Then extrapolate numbers from that with updated information from public wallet providers, like Blockchain, and also many people are using multiple wallet for security reason.
