It is now 8.6k at Yobit and is still growing.
I am satisfied with 10k though. I dont know about miners if they need an amount larger than that to satisfy their needs and also for payment of electricity.
I think that may be enough.
15k might be way far and we might see it after the halving only.
They do not need the price of bitcoin to be so high but I am sure they appreciate it, however the market does not really care about that, the miners just like any other actor in this market needs to time the market correctly and sell their coins when they can obtain the most benefits and if they cannot do that then they lose money, it may seem to be unfair but that is just the way the market works and they need to adapt to it like everyone else.
