Right now there are big number of 2-3 ETH deposits done at Binance, which caught my attention. They look very suspicious, so I started digging - ALL of them are linked to few MASTER accounts with 20-30+ K ETH...those MASTER accounts are splitting the funds, in to smaller batches/addresses which in turn do the same .... we are talking for thousands of intermediary accounts - 1 sending to another and so on until eventually all goes to Binance in small transfers of 2-3 ETH from many, many accounts (may be same thing is happening with other exchanges, I just noticed that in Binance)

Looks like someone is trying to hide/mask the big amounts, or simply making more difficult to trace "source" of the main funds.... No idea why would anyone want to do that, but I remembered about your post I read few month ago and decided to share what I discovered today as it is very much similar to your discovery.
