Quick question:
I took the liberty of quickly checking blockchain.org - just a quick peek...

So the investment address (111mamKazi1ofZ854rKTcAxhTVuGDPhhL) had ~430BTC in it before Sunday. Still can't believe that you were trying to keep that, Nick!

On Sunday, 14th October, almost all the funds form that investment address get transferred to one other address:
18KhyaJWe7aYqeL48FQmvPTFJzBt6VUPiW 432 BTC
And that money is still sitting in that wallet.

Care to elaborate, Nick?
What's that address our money went to?

My transaction seemed to come from 17jynkLbZCtSEPXUkgFJsa2TjfAzPViq1K and/or 19pvHWwpdqgfs8Q1D3y7JaAn7H8DhuAH1V... Both empty now.

Can you please explain the details of the transaction? How did the money get paid out?
