I was contacted on social media. He was going to mine 200 btc for me and I get a profit of $4870. He told me to create a black chain account but we never use it. Instead when I bought the btc he send me a link to put it in for it to be mined which I did . However when it was te to withdraw money I was told I need to make a deposit of 1200 to get the money by Trust Markets • trustma[email protected] which I refuse to pay am I right not to pay?
