At what point does this border a scam? You can't sell when it matters the most. This isn't the first time. And this isn't the only one down.
It sounds like a pretty dumb scam if you as me.
And before you mention it: yes, that'd likely be illegal under US law, but still, it's a scenario.
There are certainly "cheating" exchanges out there but cheating by stooping trades every once in a while is absurdly inefficient and makes people leave the exchange even if they dont know about the cheating. Exchanges can cheat way way simpler by front running the order books.
Sorry for my ignorance, but what do you mean by this? I have zero knowledge about the stock market.
