CZ served four months in prison after pleading guilty to violating the Bank Secrecy Act by not implementing an effective anti-money laundering program at Binance. The four-month sentence was a significant reduction from the three years prosecutors originally sought. ""While the DOJ just didn't have enough goods on CZ to warrant three years, I can't believe CZ is getting four months and not 18 months," Managing Director at Swan Bitcoin Terrence Yang said in a statement when the sentence was announced.
