You are saying rocks have no value? Lol. Of course they have a value. Even a common rock has a value, but less than a cent because it can be found anywhere. So no. No one is going to buy your "Akorn" for $10. Why would they? They could literally pick a rock for almost free of cost (minus a little labor lol). But lets say, you found a piece of meteorite (meteorites are rock too ) and you want to sell it for $10. Someone is going to buy it and then sell it for $100. The more demand for your meteorite, the higher the price will go. Meteorites are hard to find, hence expensive.
So if bitcoin was like picking up a rock, it would be dirt cheap. But guess what, they aren't dirt cheap. Now, why is that? You will know if you try to learn about bitcoin and how the system works.
