What evidence exactly? This is money laundering: In 2010 Wachovia Bank – now part of Wells Fargo – settled an action brought against it under US bank secrecy act to have laundered $378 billion of Mexican drug money and made a profit of $12.3 billion from it. It paid $160 million in fines and settlement costs. In 2012 HSBC was fined and settled for having laundered $7 billion of drug money between 2007 and 2008 and $19.4 billion of Iran related funds. In 2017 Deutsche Bank paid $630 million in fines and settlement for having laundered $10 billion of Russian assets. Explain to me how can launder that kind of money using BTC?
