There are 1-2 million Bitcoin users in the world.
I doubt this number. I think bitcoin users are more than this number by many times.
Yes, many doubt this number, but it is the truth.
Active users are even much, much less, only about 200-300k
Right now, I can send 10,000$ to you and you'll receive it within 30 seconds. (Not counting the confirmations)
Plus, I'd only have to pay a 0.05 USD fee (0.0001BTC).
If I do a wire transfer, the fee is going to be a whole lot more, along with the turn around time of more than 2 working days.
That's right my friend! You could do that. But nobody does

Do you understand what I mean?
Bitcoin is brilliant technology, but it's not changing very much.
Certainly not what Bitcoin hardliners are claiming.
