A rising price of BTC does is not necessarily caused by the increasing number of users. This might be an empty pump from the rich traders who dont have anything better to do with their free time. Please keep that in mind.
That can be one of the causes of the price increase in bitcoin lately, but I think the population who is using bitcoin is also increasing with the time. I can't estimate what is the real number who actually using it, but we start to see more place who accept bitcoin.
If you think that 23% of the population use BTC right now then please show us your proof. Until you can show me the hard numbers and statistics your speculation has no bearing and is not backed up by facts. Why would we believe a random person in this forum who is sometimes surely brain farting from his mouth.
