This topic will be vital if you keep updating the list by adding some not mentioned here.
To add to the list. Self-custody, Proof of Work, ATH, DCA, Decentralization, Market Cap, Halving, Mempool, and Lightning Network are important terms to know as a Bitcoiner. There is more to the list, so a proper research study needs to be done if a newbie wants to know them all.
Yea good suggestions, However it will make more sense to distinguish the terminology between technical and non technical terms for easier learning and referencing. Bitcoin trading and non trading terms could still be separated also. There is a lot to do and if that is done the thread will be a good reference point as just bitcoin dictionary here on the forum for newbie and everyone as well.
