Some one just sent 1300 bitcoins to address1 -> 0.003 fee & 0.xx -> address2 -> 0.003 fee & 0.xx -> address3 -> .. -> address1000 -> ...
By paying 0.003 each time to make block 393652,393699,393727 and few other blocks very big.. It's all about moving the same hundreds of bitcoin 1k+ times.
Mine pool / 3M ponzi sending out bitcoins to 1k+ users? quite expensive spams, no?
in one transaction, 0.0776 BTC was sent to 1NrbW4V68a2JvTnn3HgCD4wobUxUaNgrBy which belongs to an Hong Kong exchanger anxpro.com .
Some also go to an TaiWan exchanger https://www.maicoin.com
