Saying they have Bitcoin services. I told them that I have heard about people ( Scammers ) ringing offering Bitcoin trading . So I to them " Goodbye Scammer " , then I hung up and blocked them . You do the same . It's the fourth time in two weeks that I've got this type of call . They take your money, and buy Bitcoin in their name , not yours , give you fake statements and pocket the profits for themselves. They are scammers 100 % .
