What is FTX and what happened?

As a professional practitioner in the field of cryptocurrency and finance, I'm sorry to hear about the recent collapse of FTX. FTX was once a leading cryptocurrency exchange platform, but recently it encountered serious financial difficulties and ultimately filed for bankruptcy. Many users and investors lost their assets, which caused widespread concern and panic in the cryptocurrency industry. The collapse of FTX has also had a certain impact on the overall market, and many people are speculating about the reasons for its failure. At present, the relevant parties are still conducting investigations and audits, and we need to wait for the final results to understand the specific situation.
