What are our chances of ever getting any of our IPO money back?
Slim to none.
Right now, there are 2 main possibilities:
1) Labcoin is (sortof) legit, but grossly incompetent. Sam has admitted that half the IPO money is unspent. That means half of it is gone, so liquidation of all assets and a forced buyback of shares won't net shareholders much more than half the IPO amount.
2) Labcoin is a scam. You won't get money back.
Of course, there's a third possibility, being that Labcoin somehow gets this trainwreck back on the rails, produces a well-performing chip and collects good profits, but the odds of that are very small.
As long as Labcoin shares are not on an exchange, their are extremely illiquid and shareprice will not see massive fluctuations from news (good or bad). So hoping for the price to spike to IPO level (even if it's based on hype over news rather than true value) is pointless. With Labcoins track record of bad (or no) communication and broken promises, I don't see any serious exchange wanting to list them.
My advice (as someone who never held Labcoin for long, but mostly played the higher-lower-game with shares around news-updates): Get out now, before BTCT closes trading and at least recover some of your money.
