Dont kill me all like wolves - first: I dont believe in this "Unicorn" either, but ... the scam is done very well.
Why limit one per customer? I would sell 10 to anyone if its scam (on the one hand).
But the cables are funny. Even the painting is very bad.
But then I saw: What is a 51% attack
OK! 99,9999% SCAM. Just 0,0001% hope for those who ordered and payed already
