As per the statistics "Satoshi Nakamoto" mined around 1 million bitcoins in the early stages. So, he has gotten the same quantity of BCH as well.
What will happen if someday he might see his project at risk of overtaken by Bitcoin Cash. Could he be dump his BCH stake anytime?
Technically, it seems still possible. Don't forget that Satoshi may be a real person and he can really be having that much BTC and BCH at the same time. In this scenario, BCH would almost hit zero dollars.
Everything's posible. But this is highly improbable. We have too many unknown factor in the above equation. Is he a person? Is he a group? Are/is they/he alive?
We are not sure he create the bitcoin cash either.
But let's say he's alive and can sell 1 million f BCH, it could be turned into BTC's advantage and hurt seriously BCH
