Correct me if I am wrong but Citron is basically hedging their bets that the price of gamestop will fall dramatically and go bankrupt. They short-sold, so they will by Gamestop shares at whatever price it is at in the future (they want them to fail). WSB, realizing this, is artifically pumping up gamestop to the point where Citron will have to buy a crap ton of super expensive shares making the reddit people very rich in the process. So it's a battle of who is more influential at manipulating the market. Tons of people are very pissed off about it and it's really funny

When you sell a stock short, and it goes to $0, you make a profit of 100%. When you sell a stock short but it goes higher, your losses are potentially infinite
I've always wondered about the viability of capturing the portion of online sales for PC parts and other physical gaming products that people purchase because they need rapid replacement parts. I know from personal experience that there have been times I've had stuff like mice, keyboards, and even video cards die out of the blue and just gone to Best Buy or something to get a replacement the same day at a slight markup instead of waiting two or three days to have my system become usable again.
Just stock a limited selection of the most popular parts and peripherals, the most "acceptable" compromises a person might buy as an emergency replacement, and sell them to people that can't, or would desperately prefer not to wait for shipping times.
I'm glad I live near a MicroCenter!
