This is all speculation.
However i find it quite suspicious how right before the earnings report for both AMD and Nvidia the mining profitability spiked upwards and right after it spiked down. Could be a coincidence for all I know.
AMD earnings was on Jan 30 2018
Nvidia earnings was on Feb 8 2018
Around mid December Nvidia was trading at $190 and AMD around $10.
From Nov to mid January mining revenues basically went up 400% for the ETH GPUs and 300% for the Equihash GPUs.
There was mining mania everywhere, GPUs were sold out everywhere and big media coverage.
Right before AMD earnings it's stock price was $14
Right before Nvidia earnings it's stock price was $250
The amount of profit that could of been made by pumping ETH from $750 to $1400 and ZEC from $500 to $800. While at the same time buying stocks/options on AMD/Nvidia would of resulted in crazy profits.
it's conspiracy theory..... but who knows....
