No-one can be sure of the amount of people that are involved with Bitcoin, but I think it would be fair to say that there's something like 1-3 million people using Bitcoin, at least somewhat passively, at most given times. I think the number of people who have been involved with Bitcoin at some point in some capacity numbers somewhere close to 10 million, but that might be a stretch. I personally have no idea what the actual numbers are, but I would think they're somewhere around there.

There are around 40k registered accounts on 8btc ATM. Hope it helps.

Yeah right dude is impossible to calculate the exact amount of bitcoin users. But I think if the state can support and participate I think that data collection can be done, but I think it will not come in the near future. it still took a few years longer possible for the countries in the world accept bitcoin

And all we can see that the number of users of bitcoins is already huge and since we are increasing in terms of numbers of users the future is guaranteed that the early adopters who invested will be benefited and could possibly make a fortune in bitcoin.

It's estimated to be 1.2 million or lower based on the number of active addresses with more than dust in them. It could be much lower because many individuals have multiple addresses.

It's not my estimate but thank you for giving me the credit. That's an estimate that a grad student got by parsing the blockchain for all the known addresses with coin in them. Remember that's a global number, not just your country.

Yes it will be very difficult to know how many bitcoin user even do a poll not all will have care to join in a poll, and not all willimg to participate if one will not join I think it will not valid count.

I would think that the actual number of people using bitcoin is falling. It is being viewed more as a way to invest fiat to profit in even more fiat. So for most people outside this community is a commodity not a currency. If bitcoin is to be a currency and have growth in everyday usage then have salaries given in bitcoin. The bitcoin entrepreneurs have this responsibility. I believe blockchain.io give their employees bitcoins for the salaries. Others should follow.

when did that student do this estimate? is that even possible to parse more than 8 GB of data?!

also i think the number should be a lot more. because you should add users who are using services like coinbase and xapo, so you don't hold coins in one address but instead on the account and they move the funds around.

i think if you want to know the actual number of people "using bitcoin" then you have to see where they are using bitcoin and check the number of accounts/users in those places. for example in services like gyft or even using as investment so check out number of users on exchanges because people have only one exchange account.


and there are 866K registered accounts on bitcointalk
