There's been a shockingly high amount of young inexperienced devs involved in building for crypto. I remember making similar mistakes when I was starting out as a dev... except I wasn't solely responsible for systems handling millions of dollars.
"Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice.”
Why? Especially in the crypto space with its history. I think you got the sentence backwards. It should be "Don't attribute to stupidity what can be explained by malice." In my experience, that's almost always the case.
Most people you encounter throughout the day/week that somehow "wronged" you didn't do it out of malice, but stupidity, carelessness or plain disinterest.
