6. FTX Group & Alameda Research
Declared bankrupt on November 11th, destroyed after massive liquidation by its customers, this was triggered by CZ selling all Native FTT tokens, because these tokens were used as collateral or debt guarantees to borrow money by Alameda Research.
I don't think CZ sold all his FTT tokens because it provided an official letter he wrote to all the Binance workers about keeping their FTT bags. Although, the CZ tweet may trigger the massive liquidation of the FTT token. However, the major cause of it and the bankruptcy of FTX are SBF the mastermind, and Caroline which expose the situation at the wrong time.
Caroline and the FTX co-founder have also pleaded guilty, and in a recent report, Sam will plead guilty on January 3. It's funny when everything is so clear that there are still people who think that CZ is the one who harmed FTX. If FTX really has 10 billion USD in reserve, then CZ's sale of 500 million FTT is just the salt in the pool, and will not affect FTX too much.
I learned that no centralized services should be fully trusted. If we wanted to invest, invest on Bitcoin, buy it and never keep it on exchanges. Investing on centralized services and give 100% trust on them is another way of wasting money because sooner or later this centralized services will file bankruptcy.
Even if the situation that happened this year didn't happen. It's a childish idea to entrust one's investment to a stranger we only see as an influencer online and it is always good to entrust our investment to ourselves because no one knows us more than ourselves.
Before FTX crashed, we had Mt.gox, we should have learned from that and deposited money in exchange, like a deposit in the bank, they are not our money. "not your keys, not your property" this saying was spread long before FTX was created.
