The explanation sounds complicated to me even though there are no technical terms in it. I'm not saying your analogy is bad but it could use some fine-turning here and there. For me, I just see bitcoin as Money but in a digital system without any mediator or intermediary to dictate or monitor if it could be spent or how it was spent.
It is not only you, I didn't comprehend what op is saying there. And if I can even understood it a bit, it would be that, the op is saying that bitcoin is a liquid in which everyone is using cup to come and fetch with big and small cups. Op has described bitcoin with the objects around to the way he understands it. Op if I were you, I have restructure the thread as everyone is complaining about the thread. Op what do you means? Please explain it in a layman explanation.
