But what if instead of getting your house back, you're only getting the cash equivalent of what your house was worth THEN, plus some interest. Meanwhile, your house, which you no longer own, has tripled in value.
This is unironically the reason why stock trading is so heavily regulated.
If you looked at Bitcoin, whose entire pitch is that it's a poorly regulated speculative instrument, and thought "I'm going to put my house in this" you are an adult accepting unreasonable levels of risk.
Just because FTX (predictably) was run by a con man who got his whole company shut down DOESN'T MEAN that you're a victim. You gambled money you didn't have on a system you didn't care to understand and you are lucky to even get the money back.
