Brett Harrison, former chief executive of FTX USA, strongly criticized Rob Bankman-Fried's control and intimidation colleagues, and the latter offered a solution for reorganizing FTX's American management architecture.

Harrison shared his personal experience with Bankman-Fry and FTX US on December 14, explaining how he was hired "casually by text message" in March 2021 after working on Jane Street, an online trading platform in the UK.

But he pointed out that six months after Harrison took office at FTX, there was a "rift" between them.

Although Mr Harrison recalls that Mr Bankman-fried started out as a "sensitive and curious person", he pointed out that he saw "total insecurity and intransigence" in the face of contradictions, especially when Harrison proposed that FTX US establish a separate subsidiary to its management, development, design and legal teams.

Harrison added that she was not sure what caused the dramatic shift in Bankman-Fried's fickle behavior, although he suspected that psychological problems might be a "contributing factor".

Some of the negative effects described by Harrison include a series of kerosene lamps and control strategies applied by Bankman-Fried to Harrison and other colleagues to clean up the disorder at FTX US companies.

Harrison also recalled his last attempt to deal with FTX US's organizational problems with Bankman-Fry, claiming that he threatened to "destroy my professional credibility" if he did not receive an apology:

Harrison said the incident "reinforced" his decision to leave.

Harrison showed that he was carried away by the company's alleged mixed use and misuse of billions of dollars of customer assets in response to current fraud charges against Bankman-Fried and other FTX colleagues:

"it never occurred to me that the hidden behind the problems refers to multibillion-dollar frauds. In my career, I have seen this kind of problem in other more mature companies, and I don't think all kinds of problems will cause fatal harm to business success. "

If any of us are suspicious, let alone discover the truth, people will report to them immediately, "he added."

Bankman-Fry handed in a $250 million ransom on Jan. 3 and was paroled after explicitly pleading not guilty to all eight of its criminal charges.

Harrison resigned as chief executive of FTX USA on Sept. 9. 27-about five weeks before FTX's devastating collapse-where he showed that he had entered the role of a consultant.
