Wow, how can you be so sure that the world population is 8.1Billion? This is not accurate, the numbers of humans living on this earth is more than that, and no machine is capable of recording the exact number, there are loads of people that are living in the areas where there is no screening or counting for us to actually know their numbers, some are tribes that are not counted as part of the people living in the cities, because they are always in the jungle or the Amazon forest.
Every single person can't own Bitcoin, some will never be able to afford to buy It and some won't give a damn, even if it goes up to one million dollars they won't still care.
How many people are owning Gold today? I have never invested in Gold before and I don't care about having some Gold locked up in my basement because I don't see any reason why, it's not as if I will die because I don't have some Gold, it's the same with Bitcoin, it's not a do or die.
I found it on google where the current world population is approximately 8.1 Billion, I can accept if it was not accurate, then what's the accurate number? you can't just saying someone isn't accurate and you're not giving the accurate answer. Waiting for your answer, don't say there's no exact accurate number.
They don't have to buy it, just claim it through faucet site.
We're talking about the possibility everyone can own Bitcoin, not talk about someone's desire.
