Did you read the article? Lol. There was no Bitcoin transaction involved. Heck, Bitcoin was barely involved at all. Robbers basically posed as Bitcoin sellers, met with clients, then stole the money they brought with them to buy the coins with. This isn't digital currency theft, it's just your typical centuries-old run-of-the-mill robbery.
As far as this case goes, if you don't trade cryptos face to face, you have nothing at all to worry about.
