I think we can also add the term
HODL, which is one of the famous term in cryptocurrency, not only in trading but in overall for sure.
HODL means HOLDING for your position or what you bought, it was started here in the forum which GameKyuubi was drunk and making a thread about HOLDING his/her Bitcoin and not selling it, you can check the thread here:
I AM HODLING.
It was become popular, inside or outside of the forum.
