AlfredTheBest is a scammer.
Just check his thread https://bitcointalk.org/index.php?topic=5190128.msg52653007#msg52653007
He offered to sell BTC at -15% Marketrate.
I even offered him to pay more, but no reaction.
This guy just wants to drag you in Whatsapp to SCAM.

In the unlikely case he didnt want to scam, at least he is a timewaster.
In my language we call that "empty trouser"...
