Actually, not sure how anyone can say "Illiquid" as that GTGP has not only rebounded from .02 to .05,
Uhhm, actually the recent trades at .02 and .05 show that it is illiquid. In a stock that trades any decent amount the spread would not be ~150% The stock trades a few hundred dollars a day on average and sometimes does not even trade, that is pretty much the definition of illiquid.
http://www.investopedia.com/terms/i/illiquid.asp#axzz2KktTJN4k Definition of 'Illiquid' The state of a security or other asset that cannot easily be sold or exchanged for cash without a substantial loss in value. Illiquid assets also cannot be sold quickly because of a lack of ready and willing investors or speculators to purchase the asset. The lack of ready buyers also leads to larger discrepancies between the asking price (from the seller) and the bidding price (from a buyer) than would be found in an orderly market with daily trading activity
