...You won't see ANY pre-launch trading AT ALL.
You know why?
Because the Lisk chief dev posted at least one message saying not to. Before that message was spread around, I saw three Lisk trading threads.
I own some Lisk, admittedly, but I also own some IOTA: ~30'000's worth, all bought on the Nxt AE at post-ICO prices. So my conflicts of interest balance out enough to make me agnostic.

If you are going to trade Lisk, you would also have to give-up the email account or else it could be reset through their support center. It makes it difficult, but not impossible, to trade.
