Just realized that it may be the stolen NEMs from the Japanese exchange. Then the culprit just converted them into bitcoin then transferred them to his own wallet? (this is just a theory)
The 40k btc are completely unrelated to NEM. Don't spread misinformation with your dump theories.
Also, the wallets holding the stolen XEMs have already been flagged, so any signs of movements from them, like selling using exchanges or transfering XEMs to another wallet, can be traced by the NEM team.
The commission does not matter, since there are already confirmations.
And what is the point in this topic?
Only envy that someone has so much money ....
The point of this topic is to spread awareness about SegWit addresses.
