For me it looks like AM is not willing to issue profits as dividends to the shareholders. So they set up another company, which is maybe RM, holding 80% of RM's shares. Then they sell the chips to RM in a lower price, which means lower dividends as AM's shareholders would expect. Then the margin would be totally at RM's side.
======Everything above is only my assumption.======
Unless there are other companies than RM are also purchasing chips from AM, then I would highly doubt there is benefits tunnelling behind the scene.
Why do people assume FC is out to pull a fast one?
Must I remind everyone that after collecting 20,000 btc during IPO, AM proceeds to pay out 200,000 btc in dividends alone.
Financial reports are public and there is no trickery going on.
And what makes you assume RM is the only customer for gen3 chips? I assume every asic hardware manufacturer will be using AM's chips soon.
