The European Union Agency for Law Enforcement Cooperation, or Europol, has reported authorities took control of crypto wallets containing more than $19 million in cryptocurrency as part of enforcement actions against crypto firm Bitzlato.

In a Jan. 23 announcement, Europol reported that roughly 46% of assets — 1 billion euro, or $1.09 billion at the time of publication — moved through Bitzlato were linked to illicit activities. The government agency’s analysis suggested that Bitzlato received more than 2.1 billion euro in cryptocurrencies including Bitcoin (BTC), Dash (DASH), and Dogecoin (DOGE), much of which was converted into Russian rubles.
