This explains why we get those weird orders where sell offers are lower than buy offers.  

Because the coins aren't actually available to be sold/bought, they've been shoved into a MN, and stocks.exchange doesn't have the capital to cover any transactions until the MN starts paying out.  

So when you try to buy coins, the coins aren't really there.  

Or if you try to sell your coins to a buy offer, your coins aren't there either, they've been shoved off to a MN.  

This is some really shady/unethical business practice, and I definitely will not be using this site again.
