Now these people were real con artists, they had all my data, used correct chat scripts etc. It all sounded so legit I almost missed the moment they asked me for SMS confirmation code, at which point I realized it's a scam. Not being sympathetic to these guys but at least they were highly professional and inventive scammers, unlike those I mentioned above.
These guys has probably access on your jan formation either captured from a malicious site or they have an insider on banks or any firms that you previously associated for example ICOs that you've joined and signed up before.
There are so many people that can do much more realistic approach just to scam and steal money. I remember a call also last 2 years ago and inquiring about crypto which I don't remember I did joined, so I said wrong number but they keep insisting that Ive changed my number for that.
