why would you call everyone a bagholder is beyond me,
i take it this is your image of 99% of people trading their coins and stocks in these forums.
When the securities you hold are either untradable (LMB Holdings site), or trading an at least an order of magnitude lower than what you've paid for them, i believe bagholder is the proper colloquialism. A more colorful expression would be "OMG, bag of dicks!!1!"
