"What do you do, Maharrey?"

"I'm a crypto gangster. So, don't mess with me."

The world gangster conjures up images of a scar-faced tough guy carrying a Tommy-gun, right? Well, I get the feeling that's not really what a crypto gangster is. He's probably more like a computer nerd in his momma's basement. Except he has a Rolls Royce in the driveway.

OK, a Rolls? I'm still down! I don't really carry the tough-guy persona all that well myself.

But then there's the lesson – crime doesn't pay.  At least not in the long run.

Roger Nils-Jonas Karlsson is a crypto gangster originally from Sweden. According to Yahoo Finance, he created a company called Eastern Metal Securities (EMS) and offered investors plans featuring shares that were promised to make huge returns in gold stocks. Investors had to purchase the shares using cryptocurrencies including Bitcoin and Ethereum. He managed to run this scam for about 7 years between 2012 and 2019.

Karlsson promised investors if their shares failed to reach a promised value of up to 97% of their original investment, he would return the crypto to their wallets.
