so you admit that already we are point that some few people have such power to impact price.
This should be obvious that Bitmain have to much size and siting on asic boost will make things only worse over time.
Bitmain is making bigger downside moves in BTC that China central bank ridding Chinise exchanges 
this is sign of problems. People have to woke up.Why would I not admit that? I have already stated that the
ASIC monopoly and mining cartel are much more dangerous than any kind of scaling issues. Just so that we are clear, all these idiots in altcoins parading "we are the best, we will win next" will get crushed. This is the time to be watching and learning from Bitcoin, i.e. how Bitcoin combats and resists malicious actors such as Bitmain.
PS: With UASF price didn't even started falling... With their (B)AHD started fall fast
UASF is a good proposal and may actually get a lot more support now. If it avoids a chain split, price will go up. If it does split the chain and Bitmain goes through with their attack, then we will have 3 chains. What the value of each one will be is uncertain.
