The fall of Robinhood is evident, it is a self-destruction, the corruption was noticed. There will probably be a user exit from this app. Those who invest in stocks will be looking for havens in cryptocurrencies and will be realizing that decentralized applications are better and more secure.
Investing in FTX won't do much to fuel the stock squeeze however. The squeeze happened not because people were buying the stock but because people were buying the options far out of money. The far out of money call options like $60 call were very cheap. However the chance of GME hitting $60 when it was under $20 last month was a rare event. So market makers sold them cheap but those WSB bought the far out of money calls anyways.
And what happened was a gamma squeeze pretty much. The closer that price got to $60 the more the market makers had to buy to remain neutral in their position. So each contract is 100 shares. Hence if someone bought 100 contracts back in early Jan or late Dec, the market makers would need to buy up to 10,000 shares for that 100 contract position. Multiple this by thousands of contracts and you got your short squeeze.
People buying 1 or 2 shares, won't make any difference what so ever. Its people buying hundreds of call options far out of money made the biggest impact.
