This mega miner is funneling yenten through thousands of one time use throw away addresses then depositing it into holding accounts.  He is loosing half of his mining rewards in transaction fees just to hide this miners existence!  His biggest holding account is the #1 largest holder of yenten but he has many more that are probably in the top 10 as well such as this one.

And yes I am an investigator but no not junior.
