Can you share your Bitcoin address where you saved this large amounts of bitcoin?
and hope that you can also include the signed message that you own this address so that we can assure that you are legit.

Or you are planning to scam someone?
I tried checking this site blacksun.net from your email but it shows connection timeout or the site is down let me ask if you are in a big company?

Warning !!!
Beware guys it's a big money if you are planning dealing with this man always use a forum escrow to deal safely.
