I'm glad some of the media outlets still show some darn honesty and integrity, the author was accurate that cash is the main use of the illegal market and Bitcoin is still small even summing up all transactions it's good to see some views that are more comprehensive than the ones the EU mentioned.
As for the comments on that page ban cash logic lol.

Juth Judson cited estimates of about 50 percent of all U.S. cash in circulation in 2011. If applied to current data, that suggests $670 billion in U.S. banknotes is being used outside of the U.S. This dwarfs Islamic State's estimated $2 billion asset base.
It's also at least 15 times the amount of money moved every year in all kinds of so-called hidden digital payments -- through digital wallets, mobile money and virtual currencies.
If Islamic State moved all its transactions, hundreds of millions of dollars a year, into the bitcoin universe, the virtual currency's rate would spike wildly. Today, only 14.8 million bitcoins have been "mined," for a total of $4.7 billion at the current exchange rate.
