Recently, a comprehensive cyrpto currency study was conducted by the university of cambridge.Although,it has revealed various aspects of bitcoin such as total number of wallets used,number of unique users of crypto currency wallets,but finally they have said that it is impossible to know precisely how many people use crypto currency.What do you think? Can we atleast get an approximate number of total Bitcoin users world wide?

Impossible is nothing, easy to say it impossible as to get it become reality ; a lot of effort and cooperate are required from all of users.
Approximately? Maybe not, but at least almost true. To calculate bitcoin users all over the world, we need an anonymous poll. I mean, an online poll which every person could vote, start from a country to another, cooperate with exchanges to achieve that. Not impossible but not easy to do, in the end ; who wants to do that? There's no point to look after the approximate number maybe.

And how do you think you can implement that? How do you even know that all bitcoin users would answer your anonymous poll? Is there a certainty that they will answer honestly? How about multiple voting, can that anonymous poll identify if that particular user voted already? Your idea seems to be very difficult. There are many possibilities and factors to consider before implementing such anonymous poll. That approach will not also give the exact number of users, even not near to the exact number.

I agree with your point that what ever OP want is not possible because in every way we cannot get the details about the users as their are so many users who are using multiple wallet and they itself dont know how many they wallets they are holding.
