What is the official statement regarding the continuation of this signature campaign and the status of Cryptomine.io?
There is no official statement, Cryptomine ran off with their customers money.
I am actually quite surprised that the OP actually ended up paying the members of this campaign. That really is the strangest piece of the puzzle.
It was speculated that the OP is a purchased account, but I doubt it was worth so much that the operators of the cryptomine ponzi/scam would want to pay participants that much
Simple, carra23 is the escrow. Of course he will pay the participant.
