no---you can BUY all the shares you want.NOW SELLING shares may be another story.you can always do what some claim to do-----buy @ the bid and sell @ the ask !!!!! best of luck !!
It means there is nobody who will buy the stock at .0001. So if you really wanted to sell all you could do is a market order (some brokers may not even allow that) With a market order you could end up getting .00007, .00003, .00001 probably in the middle range somewhere, you just don't know.
