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.
It is hard to do because there are some person who get some too cheap bitcoin and it is hard too when you do at wallet because there are too many person who use too many wallets.
You could never know how many users of crypto because there are too many crypto or a lot of bitcoin that are waste because when the value of bitcoin was too cheap like on 2009 price then the bitcoin was not too importand if you have a double digits bitcoins or up that you can gain free. So therefore, they are okay even they left it then they forgot they password on that year.
