I'd give them a little more time to right things before filing suit.
I would too, if only because suing an LLC will likely result in nothing happening.
Just so there's no misunderstanding, and in case someone reading this didn't read my full email update my opinion right now based on all the available, credible information and the lawyers I've been in touch with is that it is still reasonable to be cautiously optimistic. We would be wise to avoid starting any legal proceedings prematurely. If any ONE of us decides to start a class action lawsuit and it turns out that Bitfloor was close to recovering and returning the funds, that will shoot us ALL in the collective foot and lose us all a lot of money unnecessarily.
So please don't consider me to be rabble-rousing. I do NOT want a lawsuit. I'm just trying to be organized, considering that so many people are affected, and all I want is to see everyone's funds returned, mine included.
