I'm thinking in the $300k/$400k range.
I don't think that it'll ever settle. Pricing is always relative.
If you look at gold now you may get the illusion of prices sticking to the $1.2-1.4k barrier when in fact a multitude of factors including demand for gold as a store of value in the future as well as the fact that fiat is constantly depreciating will mean prices will continue to fluctuate in the future. They won't stay at this value forever.
Likewise for bitcoin. I think that it will appreciate in the long run but it's hard to tell nominally how much it's going to go to, when demand has peaked, especially when you're measuring it in fiat. There are just too many variables. But I would say that at this stage, your prediction is still a wild guess.
