Its very simple, bad money always pushes out good money.
I truly honestly believe Coinbase is reputable. No sarc I personally believe in that company and I'm trying to be complimentary, although I have no personal affiliation other than having been an active historical customer. Anyway, they are/were/IIRC offering a loan product as an investment paying something like 5% APR (back when inflation was running about 10% LOL)
The problem is FTX was/IIRC offering a similar loan product as an investment paying something like 8%. Pyramid schemes always advertise larger numbers than the market can honestly support, its not like that have to actually earn the money LOL.
So you end up with rando speculator-investors tossing money at FTX, who wants to flush 3% down the drain by signing on with the "wrong" website?
Thus either Coinbase has to go out of business, get acquired by FTX, or hope FTX crashes and burns before the first two happen. Apparently the last option happened LOL, bye FTX.
The FTX business model was to get real big real fast and pay politicians for regulation to put their competitors out of business. Can't lose if you're the biggest and its illegal to compete with you. Ran out of money too quickly, oh well.
This is how markets work. The winners are not the "best" in some vague sense of goodness, they're the ones who took on the most risk possible without getting caught, and the more perfect the market and easier it is to flood capital in a different direction, the worse the effect gets.
The biggest dog on the block is always the first to keel over because they ran the most risks to get to be that biggest dog on the block.
This isn't a unique to finance situation, this happens in everything from automotive to mining to fro-yo fad restaurants.

Let me introduce you to my little friend, the biggest real estate hyperinflation in history. It's double plus ungood badthink to even hint in polite company that once the boomers are done, prices are going to implode to a level the latter generations can actually afford, which isn't much...
Another financial thing to look at, melt ups. Some markets that implode don't melt "down" then melt "up" as the ever shrinking number of people supporting the price disappear, upward pressure on prices actually increase as only the true believers are left.
