Let that sync in, is my 2c.
(Extra:The FED interest rates takes 2 years to kick in to Adjustable Rate Mortgages which where the first to fall.)
The fed did not cause the crypto crash. It didn't force people to gamble on cryptocurrencies. It didn't force them to not sell, at the top of the naked ponzi schemes they participated in.
Question, though, and coming back on topic: Did the rising interest rates trigger this (FXT)? There might be a path here, and it would not have the two-year delay of adjustable rate mortgages.
Recall FTX used a bunch of cash to save failing companies which would create systemic shock (ironic), acquire and invest lately, including in the Silicon Valley. My guess here: "1-2/3-4 Billion" is enough for liquidity, nobody is going to run on us, we are trusted, especially after us saving the world.
There was "bad event rolls" in the system and when they came, nobody can/will/would give them that amount of money.
I am sure in great times, they would also find liquidity/loans more easily -- which is what they are still trying to do. ("Everyone" is keeping cash to the chest, waiting to see what happens right now.)
The business models that relied on a perpetual supply of new capital, & other overly risky gambles become less attractive to investors when you can go get 5-7% on some boring bond with no risk.
You also have liquidation spirals as speculative investors need to sell asset X because of margin calls on asset Y. Which then causes a margin call on customer2 who owns asset X which has now gone down so they go sell some asset Z.. and so on.

Then the financial meltdown began in September of 2008.
