I didn't change anything. I didn't talk about the cost at all. Quote me where I talked about costs. You are making things up.
BTC's real value for you is the price that'd make you cash em all out.
Nothing else. From which price would you cash out? $100k? That means your price is $100k for a coin.
If this is not reasoning about the price and replacing the concepts of "price" with "desired price" then I don't even know.
And you still continue to ignore supply / demand.
Even your example about Korea is subject to this rule - they have one demand, the rest of the world has another. Why doesn't the rest of the world trade at Korean prices? You understand that comparing the local market and the General one is another mistake?
