Portuguese police and Europol have seized funds worth €70,000 ($77,200) in what they describe as one of the most advanced counterfeiting operations ever seen.

€1.3 million in fake notes sold since 2017

As Brazilian daily news outlet Sputnik and others reported on Sept. 10, law enforcement succeeded in bringing down the ring, which sold fake notes on the dark web in return for Bitcoin (BTC).

In action since 2017, the operation created €1.3 million ($1.44 million) in fake money. The leader, from Portugal, was found and extradited from Colombia this week.

According to police, the notes were some of the best-quality forgeries they had encountered, bearing features such as watermarks and holograms.

“Often they are only detected when entering bank deposits. In terms of normal trade, they are bank notes that pass quitebe a consequence of the following paradoxical phenomena: before the melt-water film is formed, the friction of ice is high and a large frictional heating occur which may result in the melting of the ice. If a thin (nanometer) water film would form, the friction becomes low which results in small frictional heating and the freezing of the water film. This suggests a region in sliding speed where a thin (nanometer) surface layer of the ice may be in a mixed state with small ice-like and water-like domains, which fluctuate rapidly in space and time. Alternatively, and more likely, heat-softening of the ice may occur resulting in a thin, statistically homogeneous (in the lateral direction) layer of disordered ice, with a shear strength which decreases continuously as the
