There seems to be an analogous concept of the Second Law of Thermodynamics - everything in society will tend towards scams if not actively opposed.
This is like a fractal scam, you've got gambling against the house (already a scam) with crypto (so there's no regulators to stop them rigging the games) and then instead of waiting for statistics to take their course they just run away with everyone's money.
Don't forget the final dimension of the scam where they also scam the affiliates by doing a rug-pull. Scam-ception.
Once you realize that many scams are scams against those looking to scam others it all becomes clear.
Then is it ethical to create a scam to scam people who are trying to scam others?
