Caller: (02) 8311 6984 and (02) 8311 6985

I have received four calls in two days from both of the numbers.
It's a bitcoin trading company who insisted that I signed up for more information (I didn't).
When I said they should have my email address if I signed up they said they did, but could not tell me what it was (because they didn't have it).
It's a high-pressure, unsolicited sales call to invest in bitcoin trading.
The promise is that you make money when bitcoin's value rises, AND when it falls - on average, $1000 a day!
SCAM.
