I received a phone call today from the UK number 020 7616 1383. I didn't answer as I was driving at the time.
I've checked the number through Google, and several sites report it as a financial services scam site that is attempting to sell Bitcoin.
Has anybody else had these types of call? I'm wondering how they got my number as well.
I think just like the ad we see is tailored, so also is the source of the call came from. It would have been from a site that a particular verification has been done the most common of it would be sites where there is an element of freebies probably faucets or some referral program because quality exchange sites have some serious control over data provided to them while the others are mostly about what they can get. I all boils down to being careful where you put your details and never be greedy to make money.
