I think the current rise we are seeing is somewhat related to them manipulating the price to maintain their profitability.
Can you prove that miners are manipulating the price, or is that just an conspiracy fantasy from your imagination?
Although it is impossible to tell if miners are doing anything to boost BTC price (personally I doubt any direct miners hidden agenda),
but from the other hand it is certain that Chinese market is the main factor responsible for recent price surge.
But this time it is Chinese + everybody else. Europe in fear of markets destabilization by brexit, US because negative economic forecast of FOMC and of course, last but not least - the halving.
