I agree that this is the nature effect of building tools, that anyone can use, so some will use it for good and others for bad. We literally don’t hold gun manufacturers responsible for murders committed with their guns, and the clear purpose of their product is to do harm.
I also agree that tools which promote or allow investors to interact without sacrificing control of their assets is the goal of cryptocurrency interactions. The main security of crypto is keeping your crypto in your wallet, protected by your keys. Thorchain allows this, and when they perfect their liquidity pools I suspect the TVL will go through the roof.
