I already lost a lot when I even bought those Bitcoins at $18,000 so the best thing I can do is to gamble it and earn more bitcoins to decrease my loss or breakeven it.
This kind of thinking will get you into bankruptcy if not in deeper debts. Everyone has ups and downs in life, imagine if we all went gambling on downs, we would all be in deep shit.
Either call it a lose and get out what you can and learn to live with it or go short with bitcoin, since ATH you could have earned that $18K back many times and you still can. Earn it, don't gamble it.
