This was not a question and let me give the possible reason. There is no major negative news and thus it is not because of it. There are next gen of ASCIs which had made mining easier. These are being tested by some pools and cost of mining btc is reduced because of this. They can thus sell for less and thus prices have reduced.
this doesn't even make any sense and you are wrong about some parts. i made them bold.
first is the fact that there was only talk about a big company in Japan releasing their new ASIC that they claim is more efficient than Bitmain's ASICs. i don't think it has reached any "farms" (not pools) yet.
second even if they already have it and it costs less for them to mine bitcoin that still doesn't mean they are going to sell it for less! that is not even a logical human behavior.
imagine this, you are in a signature campaign and lets say they pay you 0.01
BTC per week which you sell. if next week they pay you 0.015
BTC and price is $7500 will you sell your coins for $6000 per bitcoin? then why do you think miners will sell it for anything lower?
I am in agreement with your point, no miner will sell at a lesser price Even though they have profound another means of mining with low cost. Even hackers don't sell at low Price.
