In today's digital age, the immutable properties of the Bitcoin database accurately carry the mutual promises of Bitcoin holders, which can quickly calculate the quantity and transfer each other.
As a final note, Bitcoin is hard to come by, and if 21 million people buy one each, they will never be able to buy it again.
Yes, the value lies in the people. In fact that is the same for everything if you should look how they work, they have value because we the people say that it has value. When people lose faith in something, then it wouldn’t have any value any longer. Bitcoin is not the only thing that has value because of demand and supply, that is the same thing with the USD, and other currencies, they have value because of there is the demand for it, if there is no demand for it, then that value wouldn’t be there.
So, it’s quite funny when some people would come out and say that Bitcoin doesn’t have any true value, they are forgetting that the true value of everything lies in the demand for it.
