Good Morning,
in the forum post are a lot of private keys (i think so 10000 pieces).
the forum post is from January 2017, i have taken me one pk from the middle of the list.
And it worked,
i have now the money, and i donate 75% of this.
Thank you for your replies.

Best Regards!

EDIT: I donate 50% , i take me 25% and i will give the owner 25% back!
