The main topic here is not that price could be "6k to 8.5k" it just means the volume was mainly there which is why there is less volume above, if you reach above levels it will be easier to go up and down. That is why we were able to rush to 20k so easily, after breaking 10k, there are not many sellers, sure there are not many buyers as well but those buyers could come around when they see the price going up and hope that sellers do not show up when that happens. Just even last year we managed to get from 3k to 13k all thanks to less volume at higher levels.

If we could manage to break 11.5k one day, it will be once again easier to break towards 15k yet again since it requires less money since there are less sellers. You end up buying all sellers coins (most of them at least) after you reach to 9-10k anyway.
