Right, it doesnt matter the number of people using people, as we know that it grow every day

Well, If you will count all the people who are using Bitcoin, that would be impossible. Range maybe but the exact number of people using it ? You cant. Because everyday, there is always a member who will be using bitcoin since bitcoin is introduced across the world.

The estimation is calculated by the amount of transactions being done. We cannot know a certain accurate number, but we can know that its only going up.

Exactly its going up for sure and its really hard to find the actual number of users as it is a decentralized currency and there is no official record to come to any conclusion.

Well I don’t think there is a possible and easy way to know exactly the number of bitcoin users right now because bitcoin is mostly anonymous and one person can have a lot of accounts.

It’s not totally impossible but if you have the intention of determining the number of people using bitcoin, it won’t be as easy as pie but what’s the point of this, you just know that there are more and more people join the bitcoin world everyday and bitcoin can’t stop growing every minute.

Well BlockChain just reached 100M transactions just recently, so from there you can probably have an idea.

Blockchain wallet or transaction volume is by no means an accurate representation of the actual Bitcoin users. Many sites utilize Blockchain.info's API to send transactions and they are probably included in the count. If you want a slightly more accurate but still extremely inaccurate representation, you need to find the total unique address seen and divide by 100. Or if possible, just try to collate the total verified users from the various exchanges.

Yeah, well you said moreover if based on the transactions that appear in blockchains I think it would be difficult to calculate the number of users bitcoin. And I think now there is no thing that is capable of calculating it. To me it does not really matter, because it is not too intrusive. thanks

yes even one person can have dozens maybe hundreds bitcoin address, it will be hard if we want to estimate how many bitcoin users simply by counting the number of bitcoin address is already in use.
