Im interested to know how many people are actually now involved in the bitcoin world, Is there anyway to find out a rough idea of the user base so that we can come to a conclusion on what kind of adoption we are currently at? It seems difficult to gauge since this forum alone has several duplicate accounts from the same people.
. /r/bitcoin has 180k subs to it so would it be safe to assume if we included all miners, users holders and whoever else that we are still at under 1 million users? If this is the case then we still have a long way to go.
Does anyone have any more accurate guesses or way to determine the market?
No one knows the accurate numbers of people who hold bitcoin, all I know there's a thousand bitcoin holder in this industry.
And I don't know if there have the history record to trace the bitcoin holder through their bitcoin wallet addresses, is that possible to determine it?
No, no one stores information about people using bitcoin through their wallet address. Bitcoin is completely secure, owner, no one knows about the money they have. I'm sure of that. When it comes to the number of people using bitcoin, we can use surveys to get more information, but that's relative information, it is not exactly accurate.
