i think that there are a lot more people that are using bitcoins because there are even shops dedicated for bitcoins where people buy and sell stuff for bitcoins every day

i would predict that at least 100 million people use bitcoin from time to time because a lot of people know about it so they might be using it sometimes too in my opinion

Its hard to know how many people using bitcoin and have a bitcoin. But I guess million people using it and many other country. Bitcoin is now so popular because of the price .

I think it is between 200,000 to 500,000 users. We have about 800,000 users account here, but I think we just have about 100,000 unique users.

It's impossible to determine the number of people who using bitcoin. because one person can have some wallet. in what way we can determine the number of people who are actually using bitcoin?

actually no one know the actual number of the bitcoin user/

Yeah the community is growing now and same we can expect in future too, we will more businesses and companies entering into it which will take bitcoin price to next level.

I think here is no way to determine who uses bitcoin because we don't even know who is the people who we transact is, right?

I don't think so there is a proper way to detemine the number of people who are using bitcoin but i would say there is small percentage of all population that uses bitcoin.

There is no clear data about user base of bitcoin. I read that according to report of experts from Juniper Research that estimated user base was around 1.3 million in 2014.

This report was published last year (2015) and I haven't hear about their recent, updated version of the data. They predicted that active Bitcoin users worldwide will reach 4.7 million by the end of 2019.
