I somehow don't see a legit company here, so will first call them to establish if this is correct. If they make me believe they are real then I will most probably go.
But on Monday I am expecting new hardware to arrive, so I will be busy setting these up. I will follow up on this for sure.
If you ring the CMS number, I think the conversation will go a little like this:
Cyper: Hi. Can I speak to Rebecca Saunders?
CMS: Who?
Cyper: Rebecca Saunders?
CMS: I think you might have the wrong number.
Cyper: David Brown?
CMS: Who?
Cyper: Michael Richardson?
CMS: Who?
Cyper: Are you building an asic bitcoin miner?
CMS: A what?
Cyper: Nevermind.
Now please everyone create a list of questions that can easily and unambiguously reveal that this indeed is a scam when asked over the phone.
And another list in case it is worth going there in person.
