The hard part of extortion has always been getting paid. It's always involved exposure ("meet me there with a bag of money") or been subject to limitations (wire transfer clawbacks, cash withdrawal limits, etc), until now.
Right now anyone in the world can fill an insulin syringe with cyanide solution, walk into supermarkets (too big to properly secure, and there's too many supermarkets to prevent it), and inject it into random plastic coke bottles. People will stop drinking coke, and then Coca-cola will be willing to pay hundreds of millions of dollars to make it stop. Ten years ago, the extortionist would then have to meet somewhere to collect a bag full of money, and that's where the risk comes in. But now they can simply send coca-cola a bitcoin address and get paid anonymously risk-free. You can design extremely profitable low-risk crimes.
The question then becomes, if more people were given the ability to steal risk-free, would they? Anyone who has spent time in the crypto ecosystem has already learned the answer. They will. This is why nearly every exchange gets 'hacked' and so many darknet vendors pull exit scams. It turns out a lot of the reason most people are good all the time has more to do with fear of getting caught than virtue.
The world is about to become a very scary place.
Be the change that you wish to see. Money won't make you happy.
