Bitcoin Investment Scam

I was somewhat recently contacted trying to scam money from me to “invest” in bitcoin. I am reasonably sure this is scam because after hanging up the phone and blocking the numbers they kept calling me from different numbers all over Europe.

The numbers they have used to call me so far are:
+43 720 360747
+43 720 143023
+34 930 30 18 46
+43 720 971760
website: capitalfx.co

After multiple times of telling them I merely was not interested, they kept calling, I pretended once to go along and as soon as they offered me to show me their site they asked me to install AnyDesk. Which truly was the one thing I didn't do.

In order to get them to stop calling I threatened their operation with a police report (which I did submit). they stopped calling me.

I can't remember the name of the company they claimed to represent. Something like CapitalInvest or CapitalFX c. They also start with a guy asking you whether you speak English or French, which seems to imply they are targeting France, Belgium, Switzerland.

This may be a new type of scam. I don't know how often these happen.
