Did you even read the thread? I have explained to you already why dollars are valuable. Fact is: you cant say why bitcoin is valuable because a bitcoin you transferred to me HAS!!! no value.
Water has value. Food has value. Nobody will discuss this. Sometimes it costs more (desert) sometimes less (rainforest). But it has VALUE!
Now Bitcoin? Its NOTHING and you know it! Thats why you are saying: Look at the dollar, it has not value too (which is incorrect).
Its like the fat boy saying: Yes I am fat but other boys are fat too, so its ok.
You say: The dollar has 0 value so it is ok that bitcoin also have 0 value.
Its not ok. And your comparison is false as dollars have value.
Calm down a little. I'm trying to explain you where the mistake you are making actually is. If you don't want to hear what I say you, then it is no use discussing it any further...
