I'm thinking the actual money laundering is in bitcoin FEES, not bitcoin itself. Not the first time I've seen an article like this.
"An unknown Bitcoin investor is paying tens of thousands of dollars in transaction fees to move a small amount of BTC.
According to the latest block explorer data, the user sent a total of 0.01088549 BTC worth $194 to an unknown wallet and shelled out 2.66 BTC worth $47,000 in transaction fees.
The transfer was initially sighted by the automated distributed ledger tracking tool known as Bitcoin Block Bot."
