Your motivation is pretty obvious and I think I already said that.
You are trying to say that the "people" are too stupid to make a password that you "crypto guys"  cannot crack.
And what other reason for that if not to indulge one's poor ego?
Well, you are wrong. And we are here to help them proving that you are wrong - that is our motivation.
Maybe not because we care about them, but because wy love proving arrogant people to be wrong.

Crack my password, mr crypto guy, if you are as smart as you are pretending to be.
It holds thousands of bitcoins - that should be enough of the motivation.
