The vast majority of lawsuits are either abandoned or settled before trial.
So very true, with the focus on "abandoned." Three reasons:1) People who lost legitimate money, but it was OPM (Other People's Money). They just need to a piece of paper to CYA (Cover Your Ass, in this sentence Cover Their Ass)
2) People who lost illegitimate money. The possibility of having to document the legitimate source for the money lost is way more frightening than the amount of money lost. Remember this is Bitcoin, something that the majority of people involved use for laundering, tax evasion, spouse evasion, run-of-the-mill fraud, etc.
3) Plain embarassement. The amounts lost may still be small enough that the financial loss is smaller than the dignity loss suffered when having to make a deposition about the circumstances of the loss.
Edit: Here's the very poignant advice from Gavin regaring (3):
If you "invest" in them then please lick your wounds quietly when they implode.
