http://www.iwalletworld.com/U2ZR8A.php Only click when clean and safe. I then could log on to this place: https://mcx.ltd/transactions A non.bitcoin wallet with 4 bit coins. The email address is connected to lulzsec which I thought was dead and buried. My mobile number is hardly known by anyone and blocks all but family.
It seems like a curious con and I wonder if anyone knows what they are trying to do.
Could you give us a little more context? A wallet with bitcoins worth 20k$? What is it with all these numbers? How did you get to be contacted? Have they shown any other signs of being alive?
