The funny thing is that maybe Coinex is scrapping for all the dust they can find now, without ViaBTC those consolidations might be something they really can't afford after that hack. Or maybe it's ViaBTc sending everything they can find to cover the balance sheet!
Could also just be cleanup after the hack. Look we have coins in 1000s and 1000s and 1000s of addresses. Lets put them all into cold storage instead of having to move them all over the place for when people withdraw.
We have seen other exchanges do it. It's just amazing that so many exchnages let it get this bad.
