ETH is now centralized. 46% of ETH belongs to Coinbase and Blackrock. They can dumpt it whenver they want . Also its handeled by Amazon servers. They can shut it down wheneve they want. This reminds me of the Canadian Cannabis stocks when a new law would pass or license granted. Meant absolutely nothing. Fodder for the sheep.
They can't "dump" it, the money is there but it doesn't belong to them. If they sell all their ETH and then people ask their ETH back, then what? Or if they sell and people sell there as well and there is a financial difference? How are they going to pay for it, out of pockets? What do they gain from it as well? Shorting ETH to make a profit?
I think we need to think this through, and it looks like there is no reason for them to do anything illegal, because if they use others ETH to sell and dump the price, they are located in the USA and SEC would destroy them, not only they will be given a penalty worth tens of millions of dollars, there will be jailed people as well. Doesn't make sense to me at all.
