Fake Bitcoin mining trader named Mary Brown (@mary_brown_229 on IG) from a company called GMX Trade (gmxtrade.com) on Instagram guarantees huge profits on Bitcoin mining within 9 hours and then after you invest, she says profits can only be withdrawn after taxes, a signal fee and an amount for a private key is paid which runs in the thousands. She is never able to speak on the phone. A friend in network is hacked and separately interacts with you and encourages you to invest citing their own profits that they supposedly withdrew. You will never receive your money. Everything is done with a false sense of urgency during the time your friend is locked from their IG account.
