Maybe you are making fun, here? But,I sense that the bitcoin space is expanding and there are various competing whales.. sure sometimes, there may be some coordinated success and signaling... yet I believe that the actors are fairly complex and diversified and sometimes work together and sometimes compete, and there are so many exchanges, too that can cause signaling and leading and following.
I'm keeping my eye on the exchanges ... and when China moves, the rest follow. The volumes seem to be "scared/affraid" in The West ... they always wait China to make the first step.
The West needs a market opening for BTC ... to have more confidence or determination to lead the global price of things!
And with China ... I don't really know if they are against each other in a competition. But I do know there is some kind of cartel... Imagine those miners doing more than they need... what do you think they will do with the surplus? They will try and increase the price to increase productivity! Its the only way to increase profits!!! By pumping the price!
You can say that you are keeping your eyes on the exchanges all that you want, but that does not make your assertion true.
Correlation and causation is not the same thing. Regarding exchanges we have a bit of a symbiotic relationship, and some times one exchange or set of exchanges will push the price more than others, but it's a BIG ASS myth that China controls exchanges and/or mining merely because there exists a lot of volume there.
We do not even need to arrive at a conclusion that some of China's volume is fake in order to understand that trade action in China does not completely (or even largely) control the price. Also, volume is achieved in China too due to low or non-existent fees which inspires the use of bots and frequent trading on low price intervals.
Your point regarding miners driving the price, also, makes little to no sense and seems to be a further attempt at describing bitcoin as some narrow phenomenon pushed by a small group of folks and/or entities. It also logically makes little sense.. Sure there is some incentives for miners to attempt to push up the prices, but at the same time, the bitcoin market is a lot more organic and larger than you make it out to be with a lot of players around the world.. developers, exchanges, hoarders, speculators and increased adoption, which also fuels demand.
