Sam Bankman-Fried Sentenced to 25 years in prison.
Sam Bankman-Fried, the founder of the now-defunct FTX crypto exchange, was recently sentenced to 25 years in prison. This verdict came after a month-long trial where Bankman-Fried was found guilty of seven counts of fraud and conspiracy. The charges were related to his role in the collapse of FTX and defrauding lenders to FTX’s sister company, Alameda Research. Despite the severity of the charges, Bankman-Fried maintained his innocence and expressed regret for his decisions. This case has been a significant event in the cryptocurrency sector, marking a dramatic fall for Bankman-Fried, who was once celebrated as a leading figure in the industry. The verdict serves as a stern reminder of the legal boundaries within the rapidly evolving world of cryptocurrency.
FTX, the defunct cryptocurrency exchange, has been making progress in recovering customer funds. As of now, they have managed to recover and secure approximately $7.3 billion. This recovery process is part of their bankruptcy proceedings.
The plan proposed by FTX’s new management, led by CEO and bankruptcy expert John J. Ray III, is to send 90% of the recovered assets to former customers. However, it’s important to note that this 90% refers to the funds FTX has been able to recover, not the total customer deposits at the time of the exchange’s collapse. Therefore, customers may not necessarily get back 90% of their lost assets.
When it filed for bankruptcy, FTX had an estimated shortfall of $8.7 billion. As of September, roughly $6.9 billion of that shortfall had been recovered, and the recovery process is still ongoing.
Those who withdrew more than $250,000 from FTX in the nine days before the exchange’s collapse will be able to pay a 15% fee on those funds to avoid potential clawback attempts. This part of the amended plan implies an expected 85% or more customer recovery.
FTX is also considering restarting the exchange by the end of June and aims to confirm its goals within a year after that date. However, the actual customer shortfall remains unknown.
