Ok.. so then what are you clarifying? They want $10,000 for it. That might be, say, 10 bitcoins. They're getting $10,000. For me, it's only $1,000.
It DOES matter what the price of bitcoin is because I said I wish I had owned bitcoin @ $100, because it would make a Neptune $1,000 for me. for me.
No, because an alternative would be to sell those Bitcoins for $10000, so the Neptune is still costing you $10000.
It doesn't matter at all what price they were when you bought them, it matters what they are worth now.
