That's a great list, i already know almost all of them, but there was a couple new for me.
Is fun to see how bitcoiners use their own language nowadays, and i say it's fun because when we talk with simple mortars, we use all of this terms like if all the people know it, and you can read in their eyes how confused they are with all these new terms for them.
Was weird to see on the list how they list fork, hard fork, but soft fork wasn't there, and that's an important term they should add.
