Cláudio Oliveira was the president of the Bitcoin Banco Group, a Brazilian financial management company that reported the loss of 7,000 bitcoins in 2019. After a nearly three-year investigation, authorities seized cash, automobiles, and cryptocurrency wallets. Brazil's authorities have approved the first Latin American Bitcoin ETF, named QBTC11. Oliveira is accused of stealing at least 1.5 billion Brazilian reais ($300 million) from over 100 victims, according to police.
