I believe the term is HODL, but yes HODL'ing is crazy if you arent part of the original team, and know nothing more about the project then what you are getting fed by a bunch of guys telling you to HODL.
I have read from someone who said HODL on this forum, that person was drunk so he typed the sentence hold into hodl, and back then it was not from the team name, but if currently hold is used as a team name in cryptocurrency maybe it could be.
