Seems... particularly inefficient. I would've thought there were easier ways.
The scheme makes no sense to me, but in society like the Swedish where banks are heavily regulated and monitored and where cash is used less and less it might be one of the last ways of laundering money. Still, they are taking SEK, buying crypto, using the crypto to buy fake stream of "music" they put to Spotify to get a meagerly pay out for played streams. The "loses" on each laundered kronor must be immense.
I find it really hard to believe that this Spotify scam is more effective than some classic Forex scam.
