Recently 3 suspects were arrested by Israel police for laundering money internationally through crypto. This money was stolen from France. This is a major international money-laundry.
Through crypto does not exactly specify it is btc, could be other crypto as well, although you did not exactly provide the source link so i would presume btc was the crypto use for the money laundry. Money laundry is a crime that has been around even before the existent of btc and crypto, it is not something that suddenly occur since the emergence of btc.
This is not peculiar to btc or crypto, money launderers can use either fiat or digital currency to carry out their crime, it is a choice they made and not because they are compelled to do so, there are many positive aspect of crypto to embrace, it should not be the negative aspect.
