Banks have always been involved in different money laundering schemes and they continue to use different loopholes in the law for money laundering. All this is due to the greed of bankers, who will always have little of the money they earn. Moreover, the money laundering scheme of Russian dirty money through banks in Lithuania and Estonia is quite old. In the case of Bitcoin, all transactions would be recorded and it would be easier to detect abuse, so governments are in no hurry to accept Bitcoin.
