It can not be predicted. But I wish this should reach out to everyone in every corner and everyone should start using the bitcoins. The government should accept it and allow the people to use the bitcoins everywhere. The bitcoin would become much popular and the value of this would surely increase still more than what will be expected. The economy market will see a great spike in profit as well.

You could start counting all createt wallet adresses. This will take you a long time. But then you will just found the amount of adresses, because a lot of user has more then one and some of them always create a new adress for every transaction they made. And then there are so many lost account who will never ever be used. So i think you could treasure the amount of users!

The system can count how many addresses were made but it is impossible to know the actual count of users because one user uses many addresses.

I think by collecting every wallet and registered account can predict the number of each user, even if it does not really match. because everyone can generate some wallets and accounts.

we can not really count how many people are in the world but many are well known and know the bitcoin but those who know bitcoin talk.org in my million also.

I think you cannot speculate the number of people using bitcoin exactly. Because, a user can create many accounts as his wish. If someone can say the total number of bitcoin user, it might be the total registered users (of an exchange or an online wallet) of a company, not the actual number of peoples.

Especially when you consider that current fiat related payment platforms are also moving forward, where the cost of using it for people is zero, and all payments are instant. Another plus for these people is that they also enjoy buyers protection. I don't think we'll ever come to a point where even a small or medium country is feeling the impact of people transacting with Bitcoin.

The majority of Bitcoin owners speculate on the use of Bitcoin. They really do not understand blockchain technology, they coin Bitcoin as a property and want to buy as much as possible.

this question does not make sense! someone who has common sense knows that no one can guess the actual number of bitcoin users because one of the nice characteristics of bitcoin is you can use it anonymously! many people who use bitcoin want to hide their identity because it is also used in illegal activities! from that alone it's very impossible to know how many numbers of bitcoin users ...
