What kind of scam is it and how track they down please?

Hey there,
Here Dave, in France. Put my savings on crypto. and been contacted but someone trading, to invest on tradefxgold.com.
Now to get a cash out, they ask for ID. copy, bill copy to prove Adress, and selfie.
What are the risks and how can I track they down please ? They send mail ( like fake bank asking for authentification documents ) and keep answering on WhatsApp…
Getting the name of this fake trader would help.

Thanks
