Food for thought.  

   Is the problem digging or dumping?  Digging, in and of itself, will not cause the price to drop.  Dumping will.  There are several ways to end up with dumping.  

a) dig up a bunch of clams and sell them off as fast as you can.
b) own a lot of clams, then get butt hurt and dump them all on the market.
c) win a large amount on JD and dump them just to get the BTC.  
d) inherit clams, then dump them.  
e) people panicking over rumors.  

    Just throwing it out there.
