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.
This is a criminal activity that can be done with any currency or fiat money, not just Bitcoin. This is where criminals can take advantage of using Bitcoin to remain anonymous. So don't look for negative aspects of Bitcoin for a few isolated incidents. Rather, we need to look at the positive things of bitcoin.
