I watched a documentary on BBC yesterday about Sam Bankman Fried, once a 'crypto king richest man in the world' now awaiting trial on a raft of fraud charges with investors having lost billions. I don't get it. I don't understand crypto at all, it looks to me like a massive con in which investors are offered eg 10 million dollars worth of Unicorns for only 1 million investment, please pay in dollars, cash. Similar to Fyre Festival without the mud, a massive scam with no substance to it. Yet crypto still has credence in the financial world, so I must be wrong. Right?
