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.
Good point. We don't know that the digger is dumping at all.
We do know that all the coins he digs go to poloniex, and then most go to JD.
We can't tell the difference between:
1) digger deposits to poloniex and sells CLAMs to JD investor; JD investor withdraws CLAMs to JD
2) digger deposits to poloniex and then withdraws CLAMs to JD; the poloniex step is purely to obfuscate the link between him and his JD account
Either way, the money supply is being massively diluted by digging, and the price is dropping.
