It's quite simpleBTC goes up, Miners go up
BTC goes down, Miners go down
BTC goes sideways, Miners go down
The media have called this a decoupling of miners from the price of BTC. I think this is incorrect. Nobody is going to buy miners when they are uncertain of the direction of the price of BTC. If BTC drops to $20K USD then the bid for miners will be massive and if BTC begins to move back to it's ATH then the market will be chasing miner prices. FOMO at its best.
Just have some dry powder ready.
