That's not what he did. Pseudo randomness is the closest you can get to randomness, so once you have a good pseudo randomness you can assume you have randomness. RNG are built on some 'random' event, like processors noise, that in reality are not random but aren't predictable.
Let's say you have 1 car every 15 min on a crossroad, if the car turns left it's a 0, if it turns right it's a 1. You have a RNG, people in the car know where they are going, but not you, that's pseudo randomness.
It's important to always say that any RNG is not really random, that's a mathematical fact, but once one is validated (assume you do not know where the cars will go) you can treat it like random.
Point here is that Walton could :
- Rigged the rng, so know where the car will turn
- Have more employee participating than other people
- Smart one : not rigged, but have more employee, hoping for one of them winning, having a dip in price, buy cheap.
I think the idea that they planned this failure isn't true at all, without necessarily discrediting @cryptovestor. I think more likely is power abusing employee getting away with it, who no one seems to be able to touch. Either that or a cheap marketing gimmick.
I think that NOTHING in life is worth risking reputation. And if WTC did do it like OP was saying, the next time they even attempt to pull something off like this again, that would be the end of their company. My 2 sats.
